Question

the equation of the line is y=
the order pairs are (0,2) ( 1,7)

Answer 1

Let's get the slope :
\[\text{slope}(f,x,x')= \frac{f(x) - f(x')}{x - x'} \]
So here :
\[\frac{f(x) - f(x')}{x - x'} = \frac{7 - 2}{1 - 0} = \frac{5}{1} =5 \]
Our equation is now something like this :
y = 5 x+ b

You now have to solve for b with one set of value.
