hope this helps!
Michael bought 7 pizzas from Pizza by Alfredo and 9 pizzas from Alfredo's Pizza Cafe.
Step-by-step explanation:
Cost of Pizza at Pizza by Alfredo = $3
Cost of pizza at Alfredo's pizza cafe = $5
Total amount spent = $66
Let,
Pizzas bought from Pizza by Alfredo = x
Pizzas bought from Alfredo's Pizza Cafe = y
According to given statement;
3x+5y=66 Eqn 1
5y = 3x+24 Eqn 2
Putting value of 5y from Eqn 2 in Eqn 1;

Dividing both sides by 6

Putting x=7 in Eqn 2

Dividing both sides by 5

Michael bought 7 pizzas from Pizza by Alfredo and 9 pizzas from Alfredo's Pizza Cafe.

Rmember that the form y = mx + b is a straight line whose y-intercept is b and slope is m.
On the graph you can see that the y-intercept is beteween 0 and 5.
The equations given as options have y-intercepts 6, 20, 18, and 3, in that order.
And the only equation of the options that meet that is the option D. y = 3x + 3.
You can also check that the slope of that equation is 3 and it is roughly the slope of an intermediate line between the dots.
Answer: option D. y = 3x + 3.
