1. Let's find two random points on the graph. (-3, 3) and (-1, -1)

 

2. Slope=(y2-y1)/(x2-x1)

In this case, slope=((3)-(-1))/((-3)-(-1))=4/-2=-2.

Slope=-2

 

3. The y-intercept is -3, so the equation will be x=-2y-3.

 

Answer: y=-2x-3 smiley

Sorry if it's a bit of a bother but could you put it in standard form? like Ax + By=C? Thank you!

It's actually really easy to do it yourself. Try it.

It's okay! Your solution was still really helpful. I figured the equation out, so it's okay!
