Question

Can someone help me with these.

Answer 1

Explanation:

1)

let's take any two x, y co - ordinates from the given graph:

x1, y1 = 4, 15

x2, y2 = 6, 25

slope, m = y2 - y1 / x2 - x1

= 25 - 15 / 6 - 4

= 10/2 = 5

2)

the given two co - ordinates are:

x1, y1 = -1, -5

x2, y2 = 2, 1

slope, m = y2 - y1 / x2 - x1

= 1 + 5 / 2 + 1

= 6/3 = 2
