Question

write an equation in standard form of the line that passes through the point (-2,7) and has a slope of -1

Answer 1

Explanation:

First, sub in the ordered pair to find y int

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

7 = 2 + b

b = 5

So the equation in y int form is

y = -1x + 5

This when convert to stardard form is

x + y = 5
