If you were going to graph this function what would be the coordinates of the points that you would plot? Is this a linear or nonlinear function? Explain.

f(x)= 2x+5 inputs (5) and (8)

f(8)= 2(8)+5=16+5=21

f(5)= 2(5)+5=10+5=15

Would the points be (5,15) and (8,21)?

Since X is of the 1st degree, this is a linear Eq. Therefore, your graph will be a st. line.

Smaller numbers are more convenient for graphing:

(-2,1), (2,9), (0,5).
