Solving Systems of Equations

Front

Steffen graphed two lines in order to find the solution to a given system of equations.
What is the solution? Options: (-3,-8), (-8,-3), (3,-8), (8,3)

Back

(-3,-8)

Front

Give the solution to the system

Back

(1,3)

Front

Solve for x and y
5x + 3y = 7
y = 4

Back

(-1,4)

Front

Solve for x and y
2x − 3y = −1
 y = x − 1

Back

(4,3)

Front

Solve for x and y
y = 2x + 1
y = 4x - 1

Back

(1,3)

Front

Solve:
y = 2x -11
-3y = -6x -15

Back

No solution (parallel lines)

Front

Solve:
8x + 4y = 12
y = -2x + 3

Back

Infinitely many solutions

Front

4x - 2y = 7
 x + 2y = 3
What are x and y?

Back

x = 2, y = 1/2

Front

If 3x - 2y = 14 and 2x + 2y = 6, what are x and y?

Back

x = 4, y = -1

Front

If a system of equations has no solution, what does the graph look like? Options: intersecting lines, parallel lines, skew lines, the same line (coinciding lines)

Back

parallel lines
