Question

(Fifty points.)

Two functions, P and Q, are described as follows:
Function P
y = 5x + 3

Function Q
The slope is 2 and the y-intercept is 4.
How much more is the slope of function P than the slope of function Q?

A. 3

B. 5

C. 7

D. 8

Answer 1

The answer is A. 3 because 5 is the slope in the first minus 2 the slope in the second which equals 3.

Answer 2

A

the equation of a line in ' slope-intercept form ' is

y = mx + c ( m is the slope and c the y-intercept )

y = 5x + 3 is in this form with slope m = 5

function Q has equation y = 2x + 4

the slope of function P is 3 more than function Q
