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

The first equation will go up by 2.5 and if it were changed to y=3X+2 it will go up by 8

From y=1/2x+2 to y=3x+2
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

y=mx+b
m=slope

compare
y=1/2x+2 and
y=3x+2
the only change is the slope from 1/2 to 3
the yintercpet did not change, therefor it does not shift left or right or up nor down

D is the answer
