Module 2 Test Practice

Front

What is the slope-intercept form of a linear equation?

Back

y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you solve for x in the equation 3x + 2(4x - 4) = 3?

Back

x = 1

Front

What does it mean if a system of equations has infinitely many solutions?

Back

The equations represent the same line (coinciding lines) on a graph.

Front

What is the solution to the equation 3x + 2(4x - 4) = 3?

Back

x = 1

Front

What does the graph of parallel lines indicate about a system of equations?

Back

The system has no solution.

Front

What is the general form of a linear equation?

Back

Ax + By = C, where A, B, and C are constants.

Front

What does the slope (m) represent in the slope-intercept form?

Back

The slope represents the rate of change of y with respect to x.

Front

How can you determine if two lines are intersecting from their equations?

Back

If the slopes are different, the lines will intersect at one point.

Front

What is the significance of the y-intercept (b) in the slope-intercept form?

Back

The y-intercept is the point where the line crosses the y-axis.

Front

What is the solution to the system of equations represented by the lines y = 2x + 3 and y = -x + 1?

Back

(-2, -1) is the point of intersection.
