Answer:
The slope is 7 and the relationship is increasing
Step-by-step explanation:
y=mx+b is slope intercept form.
m=slope
7 is in place of m is y=7x+30
7 is positive so the relationship is increasing.
8
I do believe it's 8
114cm
3×8×4=96
3×3×2=18
96+18=114
The formula to find the slope with given points is: Y2-Y1 over X2-X1.
