Question

On a coordinate plane, a line goes through (negative 3, negative 3) and (negative 1, 5).
What is the equation of the line parallel to the given line with an x-intercept of 4?

y =
x +

Answer 1

y = 4x - 16

Slope = (5 - (-3))/(-1 - (-3)) = 4, and using x-intercept (4,0): 0 = 4(4) + b → b = -16.
