Answer:

The slope is 1


Step-by-step explanation:

To find the slope, we use the formula

m = (y2-y1)/(x2-x1)

where (x1,y1) and (x2,y2) are the points on the line

m = (9-2)/(3--4)

 = (9-2) /(3+4)

 = 7/7

 =1

The slope is 1

Answer:

1

Step-by-step explanation:

Slope = change in y / change in x

Y-values: 9 and 2

x-values: 3 and -4

Change is the difference

9-2)/(3- (-4)) = 7/7 = 1
