What is the Slope of a line That contains (2,5) and (3, 1) Sketch the graph. Need help with this question.

Svetach [21]

Answer:

-4/1

Step-by-step explanation:

To find the slope, first plot the two points we are given on the provided coordinate plain. Then using rise/run (slope) find the distance between the two points going up and over or rising and running. So we go up 4 and over 1, this means the slope is 4/1. Since the line we just graphed is going top left towards bottom right, it is negative.
