Answer:

y = -5x + 8

Step-by-step explanation:

Equation of a line: y = mx + b

x = slope

b = y-intercept or starting point

Slope = y^2 - y^2/x^2 - x^1

Slope = -12 - 43/4 - (-7)

Slope = -55/11

Slope = -5

b = y - y^1 = m(x - x^1)

b = y - 43 = -5(x - (-7))

b = y - 43 = -5x - 35

Add 43 to both sides

y = -5x + 8
