Systems of Equations Wk 1 Review

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

Write the equation in solve-intercept form (solve for y):
3y = 2x + 9

• y = 2/3x + 3
• y = 2x + 3
• y = 2x + 6
• y = 3/2x + 6

If a system of linear equations has one solution, what does this mean about the two lines? 

• Parallel lines
• the same line 
• Intersecting lines
