Answer:
Step-by-step explanation:
The y intercept is where x = 0.
X and y are both increasing by 5.
If you add five to the bottom row of the table we see that the next row of the table is x = 0 and y = 13.
This means that (0,13) is the y-intercept and 13 is your correct answer.

If there is 23 classrooms and each has 10 then you would have to times 23 by 10 - 23x10=230
Answer:
Train A = 299 tons Train B = 50 tons
Step-by-step explanation:
Train A = x
Train B = y
x+y = 349
x= y +249
Plug in one equation into another
y+249+y= 349
Simplify
2y+249=349
Subtract 249 from both sides
2y=100
Divide both sides by 2
y=50
Plug it into the x equation to solve for x
x+50=349
-50 from both sides
x=299
