The equation that represents a line is given by y = m x + b

Starting with the initial coordinates (0,2)
2 = m * 0 + b
b = 2

Now using the second set of coordinates (4,6)
6 = 4 m + 2
4 m = 4
m = 4 / 4
m = 1

Substituting these values into the line equation

y = x + 2

Answer is C

Answer:

The line's equation is y = x + 2.

<pTherefore, option (c) is correct.

Step-by-step explanation:

The equation for the line is displayed as

$(y-y_{1}) = \frac{(y_{2}-y_{1})}{x_{2}-x_{1}} (x-x_{1})$

Given that

Line CD intersects at the points (0, 2) and (4, 6).

$(y-2) = \frac{(6-2)}{4-0}(x-0)$

$(y-2) = \frac{4}{4}(x-0)$

y - 2 = x

y = x + 2

This leads to the conclusion that the equation is y = x + 2.

Thus, option (c) is the accurate choice.

Straight angles Are extremely important in geometry. When two lines intersect , they form multiple angles. In the diagram below,

Inessa [12570]

When two straight lines cross, the vertically opposite angles created are equal, and the remaining two angles match each other as well. Suppose one known angle is x; then the two adjacent angles can be calculated by subtracting twice x from 360 degrees and dividing the remainder by 2.

Thus, the table fills out as follows:

Row 1:

Given angle <GEF = 120°

Angle <FEM is adjacent to <GEF, so
$\angle FEM= \frac{360-2(120)}{2} \\ \\ = \frac{360-240}{2} = \frac{120}{2} =60^o$

Angle <MEH is vertically opposite to <GEF, making it equal to 120°

Angle <HEG is vertically opposite <FEM, so it equals 60°.

Row 2:

Given angle <MEH = 150°

Since <MEH is vertically opposite to <GEF, <GEF = 150°

Angle <FEM is adjacent to <GEF, thus
$\angle GEF= \frac{360-2(25)}{2} \\ \\ = \frac{360-50}{2} = \frac{310}{2} =155^o$

Angle <HEG is vertically opposite to <FEM, so <HEG = 30°.

Row 3:

Given angle <FEM = 25°

Angle <FEM is adjacent to <GEF, thus
$\angle GEF= \frac{360-2(25)}{2} \\ \\ = \frac{360-50}{2} = \frac{310}{2} =155^o$

Angle <MEH is vertically opposite to <GEF, equal to 155°

Angle <HEG is vertically opposite <FEM, so it equals 25°.

Row 4:

Given angle <HEG = 45°

Angle <HEG is adjacent to <GEF, so
$\angle GEF= \frac{360-2(45)}{2} \\ \\ = \frac{360-90}{2} = \frac{270}{2} =135^o$

Angle <FEM is vertically opposite to <HEG and thus equals 45°

Angle <MEH is vertically opposite to <GEF, hence <MEH = 135°.

Rita is spending more time at home to study and practice math. Her efforts are finally paying off. On her first assessment she s

PIT_PIT [12445]

Response

After her seventh assessment, she will score above 85.

Explanation

We can represent this situation through a linear equation.

On her initial assessment, Rita scored 58, providing the first point (1, 58).

On her second assessment, Rita earned 63, making our second point (2, 63).

To calculate the rate, known as the slope of our line, we utilize the slope formula:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

where

$(x_{1},y_{1})$ signifies the coordinates for the first point

and $(x_{2},y_{2})$ represents the coordinates for the second point.

From these points, we can establish that $x_{1}=1$ , $y_{1}=58$ , $x_{2}=2$ , $y_{2}=63$ . We will input the values into our slope equation:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

$m=\frac{63-58}{2-1}$

$m=\frac{5}{1}$

$m=5$

Now, we recognize that Rita's score grows by 5 points with every assessment.

To finalize the equation of our line, we apply the point-slope formula:

$y-y_{1}=m(x-x_{1})$

$y-58=5(x-1)$

$y-58=5x-5$

$y=5x+53$

Ultimately, we substitute $y$ with 85 in our equation and solve for $x$ to determine on which assessment she will achieve a score higher than 85:

$85=5x+53$

$32=5x$

$x=\frac{32}{5}$

$x=6.4$

Since a score of 0.4 assessments is not possible, she will exceed 85 after her seventh assessment.

A small town's phone numbers either begin 373 or 377. How many phone numbers are available?

babunello [11817]

There are a total of 20,000 available numbers. To ascertain how many phone numbers are available, the number of digits in each number must be known. Here, I will assume each number has 7 digits. This leads to the format starting with either 373XXXX or 377XXXX, where each X can be any digit from 0 to 9. This results in 10 options for each X. Therefore, there are 10×10×10×10 = 10,000 distinct phone numbers starting with 373 and another 10,000 with 377, totaling 20,000 numbers.

On a dell river, a boat will pass the Colby drawbridge and then the wave drawbridge opening times.There are 60 minutes in a hour

Svet_ta [12734]

The conversions yield 45/60 and 10/60 since the common denominator is established as 60, thus 3/4 of an hour equals 45 minutes and 1/6 of an hour translates to 10 minutes.
