A quick look at the given table shows that as x increases by 1, y increases by 3. thus, the slope of this str. line function is 3.
y = mx + b. Replacing m with 3, y = 3x + b. Subbing the coordinates of any of the given points, 10 = 3(3) + b, so b = 1.
The function is y = 3x + 1. Slope is 3 and y-intercept is (0,1).
