Answer:
Image result for what is the slope of a graph?
The slope of a line is rise over run. Learn how to calculate the slope of the line in a graph by finding the change in y and the change in x.
Step-by-step explanation:
It would be C.
For example, say 1 person comes. This would be x=1. Plugging this in gives you,
y=0.5 + 1.3
This shows that C is true since x is always going to be multiplied by 0.5.
1.3 would be the base amount of time it takes to arrange since if it the y-intercept.
