Answer:
y=2x+17
Step-by-step explanation:
Given the table values as;
x 0 1 3
y 5 7 11
Take values as coordinates in x,y format to have points
(0,5) , (1,7) and (3,11)
Find Δy which equals to the gradient using two points
Δy=7-5/1-0 = 2/1=2
m=2
Take the other point (3,11) and (x,y) to find the relationship in form of y=mx+c
y-11/x-3 = 2 --------------cross multiply
y-11=2(x-3)------------open the brackets
y-11=2x+6---------------collect like terms
y=2x+6+11
y=2x+17
