Front

What does the inequality y ≥ -3 represent on a graph?

Back

The area above the horizontal line y = -3, including the line itself.

Front

When graphing an equation, what is the first point you should plot?

Back

The Y-intercept.

Front

Solve for x: 2 |x−4| + 8 = 18

Back

x = 9 and x = -1.

Front

What is the slope of the line represented by the equation y = -4/5x + 3?

Back

The slope is -4/5.

Front

Is the point (-2, 4) a solution to the system of equations?

Back

Yes, it is a solution.

Front

What is the general form of a linear equation?

Back

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

Front

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

Back

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

Front

What does the term 'Y-intercept' refer to?

Back

The point where the line crosses the Y-axis (x=0).

Front

What is the solution set of the equation 2x + 3 = 7?

Back

x = 2.

Front

What does it mean for a point to be a solution to a system of equations?

Back

The point satisfies all equations in the system.
