The way I do it is I find the slope and use the formula y-y1=m(x-x1) plug in m for the slope and y1 for 21 and x1 for 5 then solve to get the y intercept

Hey!
So to get the b value you would have to plug in the points and solve for b.
21 = 5(5) + b
21 = 25 + b
21 - 25 = b
b = -4

to check you could use the other point
-29 = 5(-5) + b
-29 = -25 + b
-29 + 25 = b
b = -4

Both of them have b equal -4
so y = 5x - 4

Hope this helps!
