What is the solution to the system of equations represented by the graph?

Back

The solution is the point where the two lines intersect.

Front

How do you determine the solution of a system of equations by graphing?

Back

Plot both equations on the same graph and identify the intersection point.

Front

What does it mean if a system of equations has an infinite number of solutions?

Back

It means the two equations represent the same line.

Front

What is the solution to the system: x + y = 6 and x - y = 2?

Back

(4, 2) is the solution.

Front

What is the absolute value equation setup for |X + 3| = 5?

Back

X + 3 = 5 and X + 3 = -5.

Front

What is the graph of the function f(x) = 2|x - 4| - 3?

Back

It is a V-shaped graph that opens upwards with a vertex at (4, -3).

Front

How do you solve the equation |X - 2| = 3?

Back

Set up two equations: X - 2 = 3 and X - 2 = -3.

Front

What is the solution to the system: 2x + 3y = 6 and x - y = 1?

Back

(3, 0) is the solution.

Front

What does the vertex of an absolute value function represent?

Back

The vertex is the highest or lowest point of the graph, depending on the direction it opens.

Front

How do you find the x-intercept of a linear equation?

Back

Set y = 0 and solve for x.
