Answer:
y=9x+9
Step-by-step explanation:
y=mx+c
You can use any of the 2 points
pnt1. (1;18)
pnt2. (3;36)
find the gradient
![m = \frac{y2 - y1}{x2 - x1}](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7By2%20-%20y1%7D%7Bx2%20-%20x1%7D%20)
![m = \frac{36 - 18}{3 - 1}](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7B36%20-%2018%7D%7B3%20-%201%7D%20)
![m = \frac{18}{2}](https://tex.z-dn.net/?f=m%20%3D%20%20%5Cfrac%7B18%7D%7B2%7D%20)
![m = 9](https://tex.z-dn.net/?f=m%20%3D%209)
substitute one point and gradient to find c
y=mx+c
18=9(1)+c
18=9+c
c=18-9
c=9
therefore the equation is y=9x+9
