The graph represents function 1 and the equation represents function 2:

a graph with numbers 0 to 4 on the x-axis and y-axis at increments of 1. a horizontal straight line is drawn joining the ordered pairs 0, 3 and 4, 3.

function 2
y = 6x + 1

how much more is the rate of change of function 2 than the rate of change of function 1?

a. 5
b. 6
c. 7
d. 8

A horizontal line has a slope(rate of change) of 0

y = 6x + 1slope(rate of change) = 6

so function 2 is 6  higher then function 1

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.

49.6 is what i think it is.
