Answer:
Write a linear function f with the values f(2)=−2 and f(1)=1.
So, this is just a different way to say two different coordinates (x, y) and (x1, y1). f(x)=y and f(x1) = y1
We have: (2,-2) and (1,1) and we want to know the equation of the line that goes through those two points.
Find the : M = (y-y1)/(x - x1) = (-2 - 1) / (2 - 1) = -3/1 = 3; M = 3
Find the Y intercept by in one of the points for x and y and solving for B
Y = 3(X) + B
I'll choose the (1,1) to plug in: 1 = 3(1) + B; so B = -2
Put them together in intercept form: Y = 3(X) -2
