Question

Determine the slope & the y-intercept of the following graphs.

Answer 1

21)
slope=5
y-intercept= -2

22)
slope=2
y-intercept= -2

Answer 2

Answer:

Step-by-step explanation:

remember that slope is change in y over change in x or (y2 - y1)/(x2 - x1)

so let’s look at two points (1,5) and (2,1)

(5-1)/(1-2)

4/-1

-4

the slope is -4

to find the y intercept, look where x = 0 and move up or down the y axis

in this case when x = 0, y is 5

so the y intercept is (0,5)

apply this to the second problem
