Answer:

y = -2x - 3

Step-by-step explanation:

The line has a slope of -2

The line passes through point (-1, -1)

Lets take another point (x, y) on the line,

Slope = change in y ÷ change in x

i.e slope = [tex]\frac{y - -1}{x - -1}[/tex] = -2

[tex]\frac{y + 1}{x + 1}[/tex] = -2

y + 1 = -2x - 2

y = -2x - 2 - 1

y = -2x - 3 (this is the equation of the line).
