Answer 2

Explanation:

We'll use the standard equation y=mx+b to solve this problem. m is the slope of the line and b is the y intercept.

We know the slope, but we have to solve for the y intercept. To do this (I mean solve for 'b'), we need to know the slope, x value, and y value. We know the slope (-2/3), x= -3, and y=8. Let's plug this into y=mx+b and solve for b.

`y=mx+b\\8=-(2)/(3)*-3 +b\\8=2+b\\b=8-2\\b=6`

Let's plug all of this back into the first equation y=mx+b.

`y=mx+b\\y=-(2)/(3)x+6`

That's the answer to this problem.

I hope this helps.
