To solve this problem you must apply the proccedure shown below:
1. You must apply the formula for calculate the slope of a line, which is:
[tex]m=(y2-y1)/(x2-x1)[/tex]
2. Where:
y2=-1
y1=-7
x2=8
x1=0
3. Substitute the values into the formula shown above. Therefore, you obtain:
m=3/4
Therefore, the answer is: The slope is 3/4.
