Answer:

y=2/3x-31/3

Step-by-step explanation:

The general equation for point-slope form is y=mx+b, where m is the slope, b is the y intercept, and x and y are points on the line.

From the information, we do not know b and we will have to find it. We can plug in 8 and -5 into the equation.

Thus, we have -5=2/3(8)+b

Multiply 2/3 by 8 to get 16/3.

Then we have -5=16/3+b

Subtract 16/3 from both sides and it cancels out on the right.

Then we have -31/3=b

So, the equation is y=2/3x-31/3
