What is the strategy for graphing point-slope form?

• Graph the y-intercept, then use the slope to move.

• Divide to find the x- and y-intercepts.

• Graph the given point, then move according to slope.

Select all of the following equations in point-slope form.

• y - 2 = 5(x - 2)

• 3x + 2y = 12

• y + 2 = 1/4(x + 4)

• y = 4x + 6

• 2y = 5x - 7

Explain how to graph the following equation...

y - 2 = 1/3(x - 3)

• Plot the point (−3,−2), move up 1 and right 3 units from there.

• Plot the point (3,2), move up 1 and left 3 units from there.

• Plot the point (3,2), move up 1 and right 3 units from there.

• Plot the point (2,3), move up 1 and right 3 units from there.
