What is the first point you would plot if you were to graph this line?
y=1/2x+6
(0, 6)

What did the student do incorrectly when graphing
y=-2x+4
The student did the slope incorrectly. They went up 2 and right 1 instead of going down 2 and right 1.

What is the first point you would plot if you were to graph this line?
y=3-2/5x
(0,3)

Solve the equation for y:
2y-3x=10
y=5+3/2x or y=3/2x+5

What did George do incorrectly when trying to graph
y=-4+3x?
George mixed up the slope and the y-intercept. The slope should be 3 and the y-intercept should be (0,-4).

What was the mistake Cindy made while trying to graph
y=-2/3x+4
Cindy made a mistake with the slope. She went down 2 and left 3. She should have gone down 2 and right 3 or up 2 and left 3.
