To move the graph up, we need to change the part of the function that dictates the y-intercept.
In this function, which is displayed in slope intercept form, we can tell what each part of the function dictates:
F(x) = mx + b
mx = slope
b = y-intercept
In the function f(x) = -3x + 2, we can shift the entire line up 1 unit by changing the y-intercept from 2 to 3.
Your new function is f(x) = -3x + 3
