You have to make the lines congruent so it is 23by10
3 gallons= 10.5
5 gallons= 17.5
7 gallons=24.5
Answer:
Slope: 1
Y-intercept: (0,3)
Step-by-step explanation:
The y intercept is when the slope reaches the y-axis line. In this case, it is given to us. Anything that is formed like this: (0, y) is the y-intercept.
Y intercept: (0, 3)
For slope, you can use the formula rise over run. 
From the picture, I have drawn the rise over run, which is
, which is also 1.
Slope: 1
Hope this helped.
I need more information to solve.
What u can do is do 3/63=5/x. so u have to get x all by itself.
3/63=5/x
cross multiply
63×5 and 3×x
315=3x
divide by 3 to the number 315
