Ineed graphing the points of c = 100s + 2800.

Step-by-step explanation:

C = 100S + 2800

so ur y intercept is : (0,2800)

ur x intercept can be found by subbing in 0 for y (or in this case C)  and solving for x (or in this case S)

0 = 100S + 2800

-100S = 2800

S = -2800/100

S = -28

so ur x intercept is (-28,0)

so plot ur intercept points (0,2800) and (-28,0)

and u have a slope of 100or 100/1

so start at (-28,0)move up 100 and to the right 1plot thatmove up 100 and to the right 1plot thatkeep following this patternur line will eventually cross the y axis at (0,2800)

y = mx + b

C = 100s + 2800

100 is the slope

2800 is the y-int

answer: a.

step-by-step explanation: the answer is a. because, you need to converge the fractions to find a solution.
