Two functions, A and B, are described as follows: Function A y = 8x + 3 Function B The rate of change is 1 and the y-intercepted is 4. How much more is the rate of change of Function A than the slope of Function B?

7

Step-by-step explanation:

Expressing Both equations in the slope intercept format : y = mx + c

Function A :

y = 8x + 3

Where, slope = 8 ; intercept = 3

Function B:

y = x - 4

Note ;

Rate of change = slope

Rate of change or slope of function A = 8

Slope of function B = 1

Difference = 8 - 1 = 7

1 mph

step-by-step explanation:

if the question is asking how much does she drive per mile then,

13 / 13 = 1 mph
