The slope is 1/4
Figure it out by finding 2 points that are on lines, and do rise over run to get from one point to the other

Answer:
1st formula 2n + 3m = 280
2nd formula 2n + 5m = 320
rearrange 1st formula to equal n:
2n = -3m + 280
n = -3/2 m + 140
rearrange 2nd formula to equal n:
2n = -5m + 320
n = -5/2m + 160
so now you have
-3/2m + 140 = -5/2m + 160
Rearrange to become:
-3/2m + 5/2m = 160 - 140
m = 20
Now place 20 into the very 1st equation in place of the letter m
2n + 3(20) = 280
2n + 60 = 280
2n = 220
n = 110
so it costs $110 per night, $20 per meal

<h3>Answer:</h3>
- The line is horizontal.
- The rise is zero.
<h3>Explanation:</h3>
Slope is (rise/run). When it is zero, rise=0. A line with zero slope goes neither up nor down. It is horizontal, not vertical.
When run is zero, the line is vertical, and the slope is <em>undefined</em> (not <em>zero</em>).
