What is a linear equation?

Back

Front

What does the slope of a line represent?

Back

The slope of a line represents the rate of change of the y-value with respect to the x-value. It indicates how steep the line is.

Front

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

Back

Front

What is the significance of the y-intercept in a real-life context?

Back

The y-intercept represents the starting value of a situation when the independent variable (x) is zero. For example, in a travel cost equation, it could represent the initial cost before any distance is traveled.

Front

How can linear equations be used in travel planning?

Back

Linear equations can be used to calculate fuel costs based on distance traveled. For example, if the cost per mile is known, a linear equation can estimate total fuel costs for different trip distances.

Front

What is the general form of a linear equation?

Back

Front

How do you graph a linear equation?

Back

To graph a linear equation, find two or more points that satisfy the equation, plot them on a coordinate plane, and draw a straight line through the points.

Front

What is an absolute value equation?

Back

An absolute value equation is an equation that contains an absolute value expression, which represents the distance of a number from zero on the number line.

Front

How do you solve an absolute value equation?

Back

To solve an absolute value equation, set up two separate equations: one for the positive case and one for the negative case, then solve each equation.
