PRACTICE QUIZ Graphing Linear Equations

A. Check to see if the ordered pair is a solution to the given equation. SHOW ALL WORK! (2 points each)

1) Is the ordered pair (1, -3) 2) Is the ordered pair (3, 2) a solution to: 3x + 5y = -8 ? a solution to: 5y – 7 = x B. Find solutions using the given “x” values. Write your answers as ordered pairs. (2 points for each solution) 3) Find solutions to: 3x + 2y = -6 using “x” values of -4, 0, and 3. First solution Second solution Third solution C. Solve each equation for “y”. Make sure you simplify the expression as far as you can. (3 points each) 4) 6x – 3y = 15 5) 12 – 4y = 3x

NAME: PERIOD:

D. Make a T-table of at least 3 ordered pairs. Then graph the solution on the coordinate plane. (4 points each) 6) y = -2x – 1 7) y = 4x – 3

NAME: PERIOD:

8) y = -x + 4 9) y = 2x – 3

NAME: PERIOD:

10) y = 21 x + 3

11) y = 3 Extra Credit: (2 points)

The extra credit will involve finding a solution to an equation.
