What is a solution to a system of equations?

Back

A solution to a system of equations is a set of values for the variables that makes all equations in the system true.

Front

How do you determine if a point is a solution to a system of equations?

Back

Substitute the x and y values of the point into each equation. If both equations are satisfied, the point is a solution.

What is the formula for the volume of a cylinder?

Back

The volume V of a cylinder is given by the formula V = πr²h, where r is the radius and h is the height.

Front

What does it mean for a system of equations to have no solution?

Back

A system of equations has no solution when the equations represent parallel lines that never intersect.

Front

What is the process for solving a system of linear equations?

Back

You can use substitution, elimination, or graphing to find the values of the variables that satisfy both equations.

What is a linear equation?

Back

Front

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

Back

Front

How can you tell if two lines are parallel from their equations?

Back

Two lines are parallel if they have the same slope (m) but different y-intercepts (b) in their slope-intercept forms.

Front

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

Back

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