Write the equation of a line with a slope of -3 and y intercept of 8

• x = 8
• y = -3
• y = 8x -3
• y = -3x + 8

Write an equation in slope-intercept form that goes through the points (-3, -4) and (3, 4)

• y = 3/4x + 4

• y = 3/4x

• y = 4/3x

• y = 4/3x + 4

Find the equation that represents the line going through (0, 2) and (-4, 0).

• y = 1/2 x - 4
• y = 1/2 x + 2
• y = 2x + 2
