Chapter 4 Review: Linear Equations

1. Write in point-slope form the equation for a line with a slope of 6, passing through (-2, 3).

• y - 3 = 6(x - 2)
• y - 3 = 6(x + 2)
• y + 2 = 6(x - 3)
• y - 2 = -2(x - 6)

Which is steeper? RAMP A: Rises 6 feet for every 8 feet of run. RAMP B: Rises 8 feet for every 12 feet of run.
