• 
• 
• 
• 

Write the equation of the line.

• y = -1x - 3

• y = -3x - 1

• y = (-1/3)x - 1

Write the equation in point-slope form of the line that passes through the given point and has the given slope:
 (-2, -1); m= -3

• y + 1 = -3(x - 2)
• y + 1 = -3(x + 2)
• y - 1 = 3(x - 1)
• y + 2 = -3(x + 1)

Find the point-slope form given a line with a slope of 4 passing through the point (3, 8)

• y + 3 = 4(x + 8)

• y - 8 = 4(x - 3)

• y + 8 = 4(x + 3)

• y - 3 = 4(x - 8)

Write the equation in point-slope form for the line that contains the points

(-2, -3) and (4, 3)

• y - 3 = 1(x - 2)

• y + 3 = 1(x + 2)

• y -3 = -1(x + 2)

• y + 3 = -1(x - 2)
