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)

What is the first step in solving the following equation for v?
7v + 15 = 4(5v + 7)

• Distribute 4:    7v + 15 = 20v + 28
• Distribute 4:  7v + 15 = 20v + 7
• Subtract 5v:  2v + 15 = 4(7)
• Subtract 7v:   15 = 4(-2v + 7)
