On a coordinate plane, a line goes through (0, 1) and (5, 0). What is the equation of the line that is perpendicular to and has the same y-intercept as the given line? y = One-fifthx + 1 y = One-fifthx + 5 y = 5x + 1 y = 5x + 5

First find slope of first line given the two points
Slope is change in y over change in x
0-1 over 5-0
Slope = -1/5
Slope of the line perpendicular to this line has a slope that is the negative reciprocal.
Slope of the new line is 5
You are given the y intercept with the first point so put these things together in the slope intercept formula
Y=5x +1

The correct answer is addition
