Question

What is the equation of the line described below written in slope-intercept form? the line passing through point (0, 4), perpendicular to the line whose equation is y = -x y = -4x y = -4x + 4 y = x + 4 y = 4x + 4

Answer 1

y=-x+4

Explanation:

The slope intercept form of the equation is y=mx+b where m is the slope and b is the y-intercept. This means b=4. To find m, take y=-x and form the negative reciprocal for a perpendicular line. m=1. Then substitute the values.

y=-1x+4

y=-x+4
