Linear Equations

Which equation represents the following graph?

• y = 3x + 2
• y = -2x + 3
• y = 2x + 3
• y = -3x + 2

Find the equation of the line in slope-intercept form. 

• y = - 1/4x - 3
• y = 1/3x + 3
• y = - 1/4x + 2
• y = 1/3x -3

Find the slope

• -5/3
• -3/5
• 5/3
• 3/5

Find the slope of the line that passes through the points (2, 4) and (6, 12)

• 1/2
• -1/2

Solve for y
8x + 2y = -10

• y = -8x + 5
• y = -4x - 5
• y = -¹/₄ x - 10
• y = -¹/₄ x - 5
