Question

Function 1: y = 4x + 5

Answer 1

B. The formula for function 2 is y = 2x + 4

Answer 2

Answer:

B) Function 1, because the slope is 4 and the slope of function 2 is 2.  

Step-by-step explanation:

Function 1 is in slope-intercept form, which is

y = mx+b, where m is the slope and b is the y-intercept.

This means the slope of function 1 is 4.

The slope of function 2 is given by the formula

$m=\frac{y_2-y_1}{x_2-x_1}$

Using our two points for function 2, we have

m = (10-6)/(3-1) = 4/2 = 2

This means the slope of function 1 is greater.
