Answer:
1
Step-by-step explanation:
Moving from (1, 5) to (2, -2), x increases by 1 and y decreases by 7. The slope of the line connecting these two points has the slope m = rise / run = -7 / 1, or just -7.
Alternatively, using the slope formula,
5-[-2] 7
m = ------------ = -------- = (-7/1). The denominator would be 1.
1 - 2 -1
