if y=f%28x%29 and f%28x%29=-3x%2B4, than
y=-3x%2B4
to sketch a graph we need two points sins we have a linear function
easiest way is to find x-intercept and y-intercept
to find x-intercept set y=0 and solve for x
0=-3x%2B4
3x=4
x=4%2F3
highlight%28x=1.333%29
x-intercept is at (1.333,0)

to find y-intercept set x=0 and solve for y
y=-3%2A0%2B4
highlight%28y=4%29
y-intercept is at (0,4)

plot these points and draw a line through:
