What is the definition of an intercept in a graph?

Back

An intercept is a point where a line or curve crosses an axis. The x-intercept is where the graph crosses the x-axis, and the y-intercept is where it crosses the y-axis.

Front

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

Back

To determine if a point (x, y) lies on the graph of a linear equation, substitute the x-value into the equation and see if the resulting y-value matches.

Front

What is the process for solving inequalities?

Back

To solve inequalities, isolate the variable on one side of the inequality sign, similar to solving equations, but remember to reverse the inequality sign when multiplying or dividing by a negative number.

What does it mean for a solution to be extraneous?

Back

An extraneous solution is a solution that does not satisfy the original equation, often introduced during the solving process.

How do you graph an exponential function?

Back

To graph an exponential function, identify key points, such as the y-intercept, and plot them. The graph will show rapid growth or decay depending on the base.
