Slope Review

What is the equation of this line?

• y = 2x +2

• y = 2x -2

• y = -x + 2

• Cannot be Determined

If you have a slope of 1/2 that means you could...

• Go up 1 and right 2 units.

• Go right 1 and up 2 units.

• Go down 1 and left 2 units.

• Go left 2 and down 1.

Determine the slope and y-intercept from the following equation:   y = 3/2x + 3

• slope:  4  y-intercept:  (0,3/2)

• slope: 1/5   y-intercept:  (0,5)
