Answer:

y = -1x - 2

Step-by-step explanation:

(-5, 3) and (2, -4)

= -1

-5 = x

3 = y

-1 = m

Remember y = mx + b

Insert numbers for equation

3 = (-1 * -5) + b

We need to solve for b to finish the equation

-1 * -5 = 5

3 = 5 + b

Flip equation:

b + 5 = 3

Subtract 5 from both sides:

b+5−5=3−5

b = -2

Finish point intercept form equation, now that we have 'b'

y = -1x - 2
