Samantha has a job delivering pizza for a local pizza place. She makes $42 each night, plus $3.50 for each pizza she delivers. Which equation can be used to find how many
pizzas Samantha must deliver in order to make $91 for the night?
(The options are in the picture)

42+3.50x=91

Step-by-step explanation:

3.50 times the amount of pizzas she delivered/x plus the total amount of money she earns at the end of the day/42 will equal 91.

it's a proportional graph.

step-by-step explanation:

8 x 5 = 40         (and you have -8x and -5y)

x= absiss

y= orderly

so you have a proportional graph.
