You want to do to one side the same thing you do to the other side.
In order to get the n by itself you divide the 25n by 25. But in order to not change the answer you need to do the same to the 70.

so n=

which can be reduced to

so n=
I would say the first choose that the vertical axis should use $0.50 intervals instead of $1.
Because this would make it much easier to read and understand and would it would also be more accurate.
On a number line, numbers always increase to the right and decrease to the left. Numbers to the right are greater than numbers to the left and numbers to the left are less than numbers to the right.
Answer:
Slope: -2
Y-Intercept: (0,1)
Step-by-step explanation:
The slope would be m. In this case our m is -2, so our slope is -2.
For the y-intercept, you just look at the constant. So our constant is 1, so the y-intercept is (0,1)
