A2 Midterm Review #2

Front

Is it a function?

Back

A function is a relation where each input has exactly one output. If an input corresponds to multiple outputs, it is not a function.

Front

Shade above or below? y ≥

Back

When the inequality is y ≥, shade above the line because it includes all values greater than or equal to the line.

Front

What is the solution to the system? (3, -1)

Back

The solution to a system of equations is the point where the equations intersect. In this case, (3, -1) is the point of intersection.

Front

Solve for x and y: y = 2x + 1, y = 4x - 1

Back

The solution is (1, 3). This is found by setting the equations equal to each other and solving for x and y.

Front

Which inequality is shown in the graph? y < -2x + 1

Back

This inequality indicates that the region below the line y = -2x + 1 is shaded, representing all values less than the line.

Front

What is a linear equation?

Back

A linear equation is an equation that makes a straight line when graphed. It can be written in the form y = mx + b, where m is the slope and b is the y-intercept.

Front

What does the slope of a line represent?

Back

The slope of a line represents the rate of change of y with respect to x. It indicates how steep the line is.

Front

What is the y-intercept?

Back

The y-intercept is the point where the line crosses the y-axis. It is the value of y when x = 0.

Front

How do you find the intersection of two lines?

Back

To find the intersection of two lines, solve the system of equations formed by the two lines simultaneously.

Front

What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions, showing that one is greater than, less than, or not equal to the other.
