Question

What is the equation of the line that is perpendicular to and

has the same y-intercept as the given line?
y=
x + 1
(0,1)
+
(50)
55 324
12

Answer 1

The given line has y intercept (0,1) and other point (5,0) so slope

m = (0-1)/(5-1) = -1/5

The perpendicular has slope 5, the negative reciprocal.

Through (0,1) that's a y intercept of 1 so slope intercept form of

y = 5x + 1

That's the third choice.
