Answer:
The slope of the line is 1.
Step-by-step explanation:
We are given two coordinate points:
- (-5, -3)
- (2, 4)
We can use the rate of change formula to find the slope of the points.
In mathematics, coordinate pairs are labeled as:
Therefore, we can relabel our points:
After we do this, we can expand the rate of change formula:
Now, we can use simple substitution to solve for m, or the slope.
Therefore, the slope of the line is 1.
