Weare asked to find the slope of the line that goes through the points (1, 10) and (3, -5) on the plane
We use the slope formula for that:
slope = (y2 - y1) / (x2 - x1)
in our case:
slope = (-5 - 10 ) / (3 - 1) = -15 / 2
The slope is negative since we see the line descending from left to right. and also such is confirmed by our calculated slope.
The fraction - 15/2 cannot be simplified any further, so that is it.
In the box that reads: the line is... look for the word "slanted" for example.
For m enter -15/2
Select "falls from left to right"
