Answer:
7
Step-by-step explanation:
The standard model equation here is
y = mx+b
Now,
x and y are the variables
b is y-intercept, it means it is the value of y-coordinate on y axis where this line intercepts on y-axis
m = slope or rate of change or angle ∅ this line making with x -axis.
now arrange function A according to standard model equation
y = (8)x + 3
now, by comparison of standard and function A
m(A) = 8 and b(A) = 3
For function B
it is given that rate of change or slope is 1 and y-intercept is 4
so for function b
m(B) = 1 and b(B) = 4
Now question is about how much slope of function A is more than slope of function B
m(A)-m(B) = 8-1 = 7
So answer is 7.
