Consider the equation y = 20x + 59. What is the slope of the line? What is the y-intercept? Rewrite the equation in point-slope form.

• Slope: 20, Y-intercept: 59, Point-slope form: y - 59 = 20(x - 0)

• Slope: 59, Y-intercept: 20, Point-slope form: y - 20 = 59(x - 0)

• Slope: 20, Y-intercept: 59, Point-slope form: y - 0 = 20(x - 59)

• Slope: 59, Y-intercept: 20, Point-slope form: y - 0 = 59(x - 20)
