Identifying Slope and Y Intercept from Equations

Why is she incorrect?

• The slope is -2, the equation should be

  y = -2x + 5

• The y-intercept is 4, the equation should be y = -2x + 4

• The slope is -1/2, the equation should be

  y = -1/2x + 5

• The y-intercept is -5, the equation should be y = -2x - 5
