The function 1.5x + 0.5y = 12 represents the number of hardcover books x and softcover books y you can buy at a used book sale.
(a) solve for y
We need to isolate y
1.5x + 0.5y = 12
Subtract 1.5x on both sides
0.5y = 12 - 1.5x
Divide by 0.5 on both sides
y= 24 - 3x
(b) Table for y= 24 -3x
x -----> y
0 -----> 24
1 ------> 21
2-------> 18
The ordered pairs are (0,24) (1,21)(2,18)
(c) Graph is attached below
