Write the equation of the line passes through the point (3,-1) and has a slope of 2.

• y = 3x - 1

• y = 2x - 5

• y = 2x - 7

• y = -x + 3

In slope-intercept form, write the equation of the line passing through the points (-3,4) and (-4,2).

• y = -2x + 10

• y = -2x - 10

• y = 2x - 10

• y = 2x + 10

Write an equation for the line that passes through the point (5, -4) and is parallel to the line y = 2x + 3.

• y = -2x + 14
• y = 2x - 14
• y = 2x - 6
• y = -1/2x + 6

Write an equation of a line perpendicular to
y = 2/7x - 5 through (2, -3)

• y = -7/2x + 4
• y = -4x - 7/2
• y = 4x - 7/2
• y = 7/2x + 4

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