Question

Write an equation for a line perpendicular to y = -5x – 4 and passing through the point (15,5)

Answer 1

y=1/5x+2

Explanation:

In perpendicular lines the slopes are negative reciprocals so the slope of other line is 1/5x

And they intersect at (15,5) to find the y intercept(b)

y=1/5x+b

5=(1/5)(15)+b

5=3+b

b=2
