Equations of Lines

Write the equation in point-slope form of the line that passes through the given point and has the given slope.
(4, -7); m = -1/4

• y + 7 = -1/4(x - 4)

• y - 4 = -1/4(x + 7)

• y + 7 = 4(x - 4)

• y - 7 = -1/4(x - 4)

Write an equation in slope-intercept form of the line:

• y = 2x - 2

• y = 2x + 1

• y - 1 = 2 (x - 3)

• y - 1 = 2 (x - 2)

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.

Write an equation for this relationship.

• y=1/5x

• y=1/2x

• y=2x

• y=5x
