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

Find the slope between the point (a+b,4m-n) and (a-b,m+2n)

Answer:

m = -3m+3n/-2b

Step-by-step explanation:

Slope is expressed as;

m = y2-y1/x2-x1

Given the coordinates (a+b,4m-n) and (a-b,m+2n)

m = (m+2n)-(4m-n)/(a-b)-(a+b)

m = m+2n-4m+n/a-b-a-b

m = m-4m+2n+n/a-a-b-b
