Question

The graph shows the linear relationship between the total sales and the amount of items purchased from the local Dollar Store

Answer 1

Answer:

A.   Y= 2x+1

Step-by-step explanation:

The reason for this is if you use the formula Y=Mx+ b it will help you solve this question so lets say you take the points (3,1) Where the 3 is the Y value  and the 1 is the X value, so now you would show your work starting by labeling the (3,1) points and label them as their value, then write your formula Y=Mx+ b and then replace those values as 3=2(1)+1 and that equals 3.

Answer 2

Answer: Y=2x+1
Explanation: The coordinates (1,3) can fit into this- 3=2(1)+1. It fits for all of the coordinates if that makes sense. Like if you fill in the x, and y it is equal. Feel free to comment questions!
