Question

How do I write the equation of Through(-2,-3),slope=-2

Answer 1

Answer:

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
