What is a system of equations?

Back

A system of equations is a set of two or more equations with the same variables. The solution is the point(s) where the equations intersect on a graph.

How do you find the solution to a system of equations graphically?

Back

To find the solution graphically, plot each equation on the same graph and identify the point(s) where the lines intersect.

What is the vertex of a quadratic function?

Front

What does the y-intercept represent 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.

What is the axis of symmetry in a parabola?

Back

Front

What does it mean for a function to have two solutions?

Back

A function has two solutions when its graph intersects the x-axis at two distinct points, indicating two different x-values for which the function equals zero.

Front

What is the slope of a line?

Back

Front

What does an undefined slope indicate?

Back

An undefined slope indicates a vertical line, where the x-values are constant and the line does not rise or fall.

Front

How do you represent an inequality graphically?

Back

To represent an inequality graphically, draw the boundary line (solid for <= or >=, dashed for < or >) and shade the region that satisfies the inequality.

Front

What is the difference between a strict and non-strict inequality?

Back

A strict inequality (< or >) does not include the boundary line, while a non-strict inequality (<= or >=) includes the boundary line.
