I just need to know if I am right:

If the equation y = 1/3x + 2 is changed to y = 3x + 2, what will be true about the graph of the equation?

A) The graph will shift up 3 units.
B) The graph will shift down 3 units.
C) The graph will shift left 3 units.
D) The slope of the graph will be changed.

(The answer i chose is A.)

A is not correct. The line will still go through the point (0,2)...that is, the y-intercept will be the same because both equations are in the form y = mx + b where b is the y-intercept.
Notice that only the m is different in the 2 equations...which is the slope.

I know that y-intercept wouldnt change. So it would be D.

anonymous · Answer

yes, D
