y = -1/2x - 3 is the correct equation

that is the answer to the equation of your question
Y = mx + c
If y = 4, and x = 0, then:
4 = -1 (0) + c
c = 4
If c = 4:
y = -1 (2) + 4
y = -2 +4
y = 2
If you plug in the different values of x in each equation, the answer should be:
2,0,-2
Answer:
28 1/32 ft pieces
Step-by-step explanation:
To solve this problem you need to get both the fractions to have same denominator, to do this we will times 7/8 by 4 to get 28/32. After this we can start comparing them. From the 28/32 we can make 28 pieces because 28*1/32=28/32
3x+15 , this expression correctly combines the like terms
