Answer:
y=12x+5
Step-by-step explanation:
y = the total cost
x = the number of books ordered
12x because each book (x) is $12
+5 because shipping and handling is an initial charge of $5
a. y=12(6)+5
y=72+5
y=77
b. y=12(4)+5
y=48+5
y=53
Answer:
y-6=1/2(x-4)
Step-by-step explanation:
y-y1=m(x-x1)
y-6=1/2(x-4)
Ok so parallel equations mean they have equal slope, but different y intercepts. Here, we can solve and get the equation:
y=2/5x-7/5
It ca be simplified to 48
