For the equation y = 1/2x + 3, what is the y-intercept?

• 3

• 1

• 1/2

• 2

How do you interpret the slope of 1/2 in the equation y = 1/2x + 3?

• For every 1 unit to the right, move 2 units up

• For every 2 units to the right, move 1 unit up

• For every 1 unit up, move 2 units to the right

• For every 2 units up, move 1 unit to the right

• Both lines

• Line B

• Line A

What is the equation of a line with a slope of -3/4 passing through the point (4, 4)?

• y = -3/4x + 4

• y = 3/4x + 4

• y = 3/4x + 7

Does the point (20, -9) lie on the line y = -3/4x + 7?

• Only if x is positive

• No

• Cannot be determined

• Yes
