Answer: y = (28/4)x + 4

Step-by-step explanation:

We'll be using 20, 144 (1) and 24, 172 (2) for this

slope = y2 - y1 / x2 - x1

slope = 172 - 144 / 24 - 20

slope = 28/4

y = mx + b

y = (28/4)x + b

We can then reduce 20, 144 by 4, 28

20, 144

16, 116

12, 88

8, 60

4, 32

0, 4

The y-intercept is when x = 0, so its 4.

Plug that into y = mx + b

y = (28/4)x + 4

30: m=30

Step-by-step explanation:

<u>26:</u> 2x+22=90

subtract 22

2x=68

divide by 2

x=34

<u>28:</u> 18+3x+21=90

add 18 and 21

3x+39=90

subtract 39

3x=51

divide by 3

x=17

<u>30:</u> 43+87+m+20=180

add 43 and 87 and 20

m+150=180

subtract 150

m=30
