Two functions are represented in different ways.

function 1:

let x = number of hours worked

let y = total pay in dollars

y = 20x + 15

function 2: a babysitting club charges a $25 flat rate and $10 for each hour.

which statements are true?

select each correct answer.

function 1 has a greater rate of change than function 2.

function 2 has a greater rate of change than function 1.

function 1 has a greater y-intercept than function 2.

function 2 has a greater y-intercept than function 1.

function 1 has greater rate of change than function 2.

function 2 has a greater y-intercept than function 1.

Step-by-step explanation:

Function 1 is given by: y=20x+15

and Function 2 is given by:y=10x+25

as we know that the rate of change of a equation is same as slope of a equation and the slope of the general form of the equation of the type y=mx+c is given by 'm'.

for function 1 the slope is:20

and for the function 2 the slope is:10

so the slope of function 1 is greater than the slope of the function 2.

Hence function 1 has greater rate of change than function 2.

also the y-intercept of a line is the value of y for which x=0.

for function 1 when x=0 y=15

and for function 2 when x=0 y=25.

Hence,  the y-intercept for the function 2 is greater than that of function 1.

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
