The picture has a graph of this function.
Plot The Graph Of Function F(x)=7x?
Y=4
F(x) = 4x - 2
Well I can't exactly draw it but I can tell you this: The graph will start at the origin, will go up as a straight slanted line, the gradient will be 7 and for every value of F(x) the corresponding value of x will be 7 times greater
