What does it mean for a point to be a solution to a linear equation?

Back

A point (x, y) is a solution to a linear equation if, when the x-value is substituted into the equation, the resulting y-value is equal to the y-value of the point.

Front

Back

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

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

Back

Front

Back

The slope is 2, which indicates that for every unit increase in x, y increases by 2 units.

Back

The y-intercept is -1, which is the value of y when x = 0.

Choose a value for x, substitute it into the equation to find the corresponding y-value, and form the ordered pair (x, y).

Front

What does it mean if an ordered pair does not satisfy a linear equation?

Back

It means that when the x-value is substituted into the equation, the resulting y-value does not equal the y-value of the ordered pair.

How do you find the x-intercept of a linear equation?

Back

Set y = 0 in the equation and solve for x.
