Find an equation perpendicular to y = 5 and passing through (-1,2).

x=-1

Step-by-step explanation:

A line perpendicular to y=5 is a vertical line

y =5 is a horiztonal line so  perpendicular line is  x= constant

The x value of (-1,2) is x = -1

So the line is x=-1

y intercept = -1

Step-by-step explanation:

y = 5

y -5

y - -1 = 1/5 = 2( x - 1)

y +1 = 2x -2

y = 2x-1

therefore y intercept = -1
