The equation of the line through the point (5,4) with a slope of 6/5 is y = 6/5x - 2. This is determined using the linear equation format y = mx + b. By substituting in the values, you can simplify to find the y-intercept.
The distance formula is

. In the ordered pairs (4, 6), the first number 4 represents the
x-coordinate while 6 is the
y-coordinate. In (7, -3), 7 is the
x-coordinate and -3 is the
y-coordinate. Substituting these coordinates results in

. Since subtracting a negative is equivalent to adding a positive, we now have
The aggregate expense for the markers is 12.
Given the three integers are
, we arrive at

We can merge the fractions on the left side:
