After Diagnostic: Semester Review

Front

What is the slope of the line represented by the equation y = 1/3x - 2?

Back

The slope is 1/3.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as x increases, y decreases.

Front

Solve for x: 10x + 9 = 4x - 9.

Back

x = -3.

Front

What is the solution to the equation 2x + 3 = 15?

Back

x = 6.

Front

What is the supplement angle to 42°?

Back

138°.

Front

What is the definition of a linear equation?

Back

A linear equation is an equation that makes a straight line when graphed.

Front

What does it mean for two angles to be supplementary?

Back

Two angles are supplementary if their measures add up to 180°.

Front

What is the y-intercept of the equation y = 1/3x - 2?

Back

The y-intercept is -2.

Front

How do you find the slope from two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What is the standard form of a linear equation?

Back

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