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

Back

The slope-intercept form is given by the equation y = mx + b, where m is the slope and b is the y-intercept.

Front

Back

Rearranging gives y = (2/3)x - 2.

Front

What does the graph of an inequality represent?

Back

The graph of an inequality shows all the solutions that satisfy the inequality, often shaded to indicate the region.

Front

How do you find the average of two numbers?

Back

The average is found by adding the two numbers and dividing by 2.

Front

Back

The solution is x = 62/3.

Front

What does it mean for a graph to be a function?

Back

A graph is a function if every x-value has exactly one corresponding y-value.

Front

How do you determine if a point lies on the graph of an equation?

Back

Substitute the x-value of the point into the equation and see if the resulting y-value matches the point.

Front

What is the significance of the y-intercept in a linear equation?

Back

The y-intercept is the point where the graph crosses the y-axis, indicating the value of y when x = 0.

Front

What is the process for solving a linear inequality?

Back

To solve a linear inequality, isolate the variable on one side, similar to solving an equation, and remember to reverse the inequality sign when multiplying or dividing by a negative number.
