Which of the following points lies on the graph of the line y = 5x - 2a. (0,4)b. (2,8)c. (-1,2)d. (4,10)

Replace x withe the x-coordinate of each point, and replace y with the y-coordinate of each point, and see which choice makes the equation true.

A. (0, 4)
y = 5x - 2
4 = 5(0) - 2
4 = -2 False
A. is not the answer.

B. (2, 8)
y = 5x - 2
8 = 5(2) - 2
8 = 10 - 2
8 = 8 True
B. is an answer.

We already know B. works.
Use the same method for C. and D.
They do not work.

choice B.

It says in the questions that it is 6.5?

(-14+3/2b) - (1+8/2b) = -5 -5/2b(-10+b) + (7b-5) = 8b-15(7/2b-3) - (8+6b) = -5/2b-11(5+2b) + (2b+3/2) = 4b+ 13/2
