Step-by-step explanation:
Answer:
Depends on what x values you want to take.
Step-by-step explanation:
So, first, you got to know the equation of a line. y=mx+c
First we find m, the gradient. We find it by doing y2-y1/x2-x1/
we get 12/-18 which simplifies to 2/3. Now, this is our gradient
With this we have, y=2/9x + c. Now take a point that was given, substitute and you will get c. I took 9,-8 and got c as -14.
Now our equation is y=2/3x + (-14)/
Now we have to find two points on it. Here we can take whatever x values you want, substitute it, and get the y.
