Find the slope of a line that goes through the points (-2, 0) and (4, 8). (use / for fraction, if needed)

Convert 4x + y = -12 into slope-intercept form.

What is the x-intercept and y-intercept of this graph?

• x-intercept: 4

  y-intercept: -2

• x-intercept: 2

  y-intercept: -4

• x-intercept: -2

  y-intercept: 4

• x-intercept: -4

  y-intercept: 2

If a system of equations has no solution, what does the graph look like? 

• intersecting lines
• parallel lines
• skew lines
• the same line (coinciding lines)

• 2a + 16
• 2a + 4 
• 4 - 1a
• 3a + 8

• 18
• 30
• -18
• -30

• x = 0

• x = 3

• x = -3

• x = -18

• x = 8

• x = 16

• x = 24

• x = 2
