Question

A line passes through point A(12,18). A second point on the line has an x-value that is 125% of the x-value of point A and a y-value that is 75% of the y-value of point A. Use point A to write an equation of the line in point-slope form.

Answer 1

(y - 18) = -3/2 (x - 12)

Explanation:

125% of 12 equals 15

75% of 18 equals 13 1/2

so the slope equals 4.5/-3 or -3/2
