PLEASE HELP AND SHOW YOUR WORK PLEASE NO FAKE ANSWERS I BEG OF YOU, I REALLY DO NOT WANNA FAIL THIS MATH CLASS.

See below

Step-by-step explanation:

7. Let's put points in this equation, 1, 2, and 3 will do.

y = 4x

y = 4(1)

y = 4

(1, 4)

y = 4x

y = 4(2)

y = 8

(2, 8)

y = 4x

y = 4(3)

y = 12

(3, 12)

Plot the points, and draw the line. See the first attached graph.

8. Let's put points in this equation, 1, 2, and 3 will do.

y = x + 6

y = 1 + 6

y = 7

(1, 7)

y = x + 6

y = 2 + 6

y = 8

(2, 8)

y = x + 6

y = 3 + 6

y = 9

(3, 9)

Plot the points, and draw the line. See the second attached graph.

9. Let's put points in this equation, 1, 2, and 3 will do.

y = 2x + 1

y = 2(1) + 1

y = 2 + 1

y = 3

(1, 3)

y = 2x + 1

y = 2(2) + 1

y = 4 + 1

y = 5

(2, 5)

y = 2x + 1

y = 2(3) + 1

y = 6 + 1

y = 7

(3, 7)

Plot the points, and draw the line. See the third attached graph.

ruth is 6 years old

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2  

if you do 1/5 it also equals .2, so that is the answer.

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
