Jenny writes the equation y = 1/2x +5.

Why is she incorrect?

• A. The slope is -2, the equation should be

  y = -2x + 5

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

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

  y = -1/2x + 5

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