Can someone please help me with my algebra 1 homework and if you can explain how it works thank you

1. y = 2m + 4

2. y = 3m + 1

3. y = 2/3m +1

4. y = 4m -6

Will answer any questions in the comments

Step-by-step explanation:

1.  1 -> 5 = 4

   6 -> 14 = 8

   8/4 = 2

   y = 2m + 4

2. 2 -> -3 = -5

   -5 -> 10 = 15

   5/15 = 3

   y = 3m + 1

3. 9 -> -3 = -12

   11 -> 3 = -8

   -8/-12 = 2/3

   y = 2/3m + 1

4. 3 -> -2 = -5

   6 -> -14 = -20

   -20/-5 = 4

   y = 4m - 6

tip $2.90

total $17.40
