Answer:

y = -2x - 1

Step-by-step explanation:

Plug in the slope and given point into slope intercept form, y = mx + b, and solve for b:

y = mx + b

-3 = -2(1) + b

-3 = -2 + b

-1 = b

Plug in the slope and y intercept into y = mx + b:

y = mx + b

y = -2x - 1

So, the equation of the line is y = -2x - 1
