2. Write an equation of a line with the given slope and y-intercept.

m = 1, b = 4

A. y = –1x + 4

B. y = 4x + 1

C. y = x + 4

D. y = x – 4

the answer is C

Step-by-step explanation:

You would take and the y axis would equal x since the m is 1 it would just be x and then since you have the 4 you would just add it to the y=x and then it would be y=x+4

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
