Answer:
a = 5 1/3
Step-by-step explanation:
a+b+b = 24
a + 2b = 24
b-a =4
a = b - 4
b - 4 + 2b = 24
3b = 24 + 4
b =28/3
substitute this in a = b - 4
a = 28/3 - 4
a = 28/3 - 12/3
a = 16/3
a = 5 1/3
Y=x+7
Step-by-step explanation: because your slope is the x value and in the coordinates the y value is 7 and you put it in the form y=Mx+b
