Question

Calculate the equation of a line that is perpendicular to the line shown on the graph and that also shares the same y-intercept.
coordinates are (-8,0) and (0,4)
Answer in simple words and in 2 sentences)

Answer 1

First, find the slope of the line from the points (-8,0) and (0,4), which is ½. The slope of the perpendicular line is -2 (the negative reciprocal), so the equation of the perpendicular line with the same y-intercept of 4 is y = -2x + 4.
