In the form solope intercept we need to find the slope and the intercept, so we can see that the intercept in the graph and is:


b=70

now to find the slope we can use this equation:


m=(y_2-y_1)/(x_2-x_1)

and we replace ywo coordinates so I use ( 0,70) and ( 10,80) so the slope will be:


m=(80-70)/(10-0)=(10)/(10)=1

So the equation is:


y=x+70
