Question

Write the slope-intercept form of the equation that passes through the point (1,5) and is perpendicular to the line y =-x + 3

Answer 1

y = -1/7x - 23/7

Explanation:

Step 1: Find slope m

m = (-4 + 3)/(5 + 2)

m = -1/7

y = -1/7x + b

Step 2: Find b

-3 = -1/7(-2) + b

-3 = 2/7 + b

b = -23/7

Step 3: Rewrite equation

y = -1/7x - 23/7
