Is the line y = 3x – 7 parallel or perpendicular to 3x + 9y = 9? Explain your answer.
Inessa [12570]
Y = 3x - 7...the slope here is 3 while the y-intercept is -7

3x + 9y = 9
9y = -3x + 9
y = -1/3x + 1....the slope of this line is -1/3 and the y-intercept is 1

the slopes 3 and -1/3 are negative reciprocals of one another...therefor, these lines are perpendicular.

Joaquin is constructing the perpendicular bisector of AB. He opens his
Zina [12379]

Answer:

A

Step-by-step explanation:

To construct the perpendicular bisector, follow these steps:

Step 1:

Set the compass to a distance greater than half the length of segment AB, place it on point A, and draw an arc across AB.

Step 2:

Keeping the same width, place the compass on point B and create another arc across AB.

Step 3:

With the ruler, connect the two intersection points of the arcs by drawing a line.

Step 4:

This line will be the perpendicular bisector of the segment AB.

Thus, option A is the correct choice.
