Answer:
x = 3y + 1
Step-by-step explanation:
You need to find the relationship between x and y before finding the y-intercept.
0-(-1) = 1
1-0 = 1
2-1 = 1
1-(-2) = 3
4-1 = 3
7-4 = 3
As x increases by 1, y increases by 3.
At x = 0, y is already 1. Thus:
x = 3y + 1
Step-by-step explanation:
To solve this system of equations, let's first add the equations together:
There are no values of 
that will make this equation true, so the lines never intersect, and therefore there are no solutions to this system of equations.
Answer:
50-45+87-25=67
Step-by-step explanation:
earning is + so +50
losing is - so -45
+87
-25
