Question

can someone help me with this I have to do like 18 other questions so if you can help me with those I would appreciate it!

Answer 1

see below

Explanation:

1.)

(0, 4)

(1, 7)

`(7-4)/(1-0) = 3`

y = 3x + b

(4) = 3(0) + b

b = 4

y = 3x + 4

Rate of change: 3 initial value: 4

2.)

(0, -5)

(1, -3)

`(-3-(-5))/(1-0) = 2`

y = 2x + b

(-5) = 2(0) + b

b = -5

Rate of change: 2 initial value: -5
