Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as x increases, y decreases, meaning the line falls from left to right.

Front

What is the rate of change in a linear function?

Back

The rate of change in a linear function is the slope of the line, representing how much y changes for a unit change in x.

What is the standard form of a linear equation?

Back

Front

How do you convert from point-slope form to slope-intercept form?

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, represented by the value of y when x = 0.

Front

How do you determine if a point lies on a line given by an equation?

Back

To determine if a point (x, y) lies on a line, substitute x into the equation and check if the resulting y equals the y-coordinate of the point.

Front

What is a system of equations?

Back

A system of equations is a set of two or more equations with the same variables, which can be solved simultaneously.

Front

How do you solve a system of equations using substitution?

Back

To solve a system using substitution, solve one equation for one variable and substitute that expression into the other equation.
