Determine whether the function is linear or nonlinear? Help

linear

Step-by-step explanation:

If it is linear, for each unit increase in x, there should be a constant change in y.

x=1, y=5

in x=2, we expect y to increase by 5 units, so 5+5 = 10, which is right.

x=3, expect 5 units increase, and we do see that as 10+5 = 15.

x=4, expect 5 unit increase, and 15+5 =20 so we see that

this is linear function, if nonlinear then we would see different changes of y for each unit increase of x.

step-by-step explanation:

the slope of a line is equal to the rise/run. in this case the line rises 2 units for every +3 units it moves
