Front

What is the solution of the equation 3w = 30?

Back

w = 10

Front

What is the y-intercept of the line with the equation y = -2x + 4?

Back

The y-intercept is 4.

Front

When graphing an inequality, which symbols use a closed dot?

Back

≤ and ≥.

Front

Is the point (1, 2) a solution for the inequality represented by a dotted line?

Back

Yes, it is located in the shaded region.

Front

Solve the system of equations: -7x - 2y = -13 and x = 2y + 11.

Back

The solution is (3, -4).

Front

What is the definition of a linear equation?

Back

An equation that makes a straight line when graphed.

Front

What does the slope of a line represent?

Back

The rate of change of y with respect to x.

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.

Front

What is the difference between a solid line and a dotted line when graphing inequalities?

Back

A solid line indicates that points on the line are included; a dotted line indicates they are not.
