How do I write the equation of

Through (-2,-3), slope=-2

y = - 2x-7

Step-by-step explanation:

Start with the linear equation formula.

y = mx+b

identify what you already have.

x = - 2 and y = - 3 m (slope) = - 2

we are trying to find b, so plug in what you have.

-3=-2 (-2) + b

simplify.

-3 = 4+b

subtract 4 on both sides.

-7 = b

set up your equation without the x and y value.

y = - 2x-7
