Slope Intercept Word Problems

Front

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

Back

The slope-intercept form is given by the equation y = mx + b, where m is the slope and b is the y-intercept.

Front

How do you determine the slope from a word problem?

Back

The slope represents the rate of change. Identify how much the dependent variable (y) changes for each unit increase in the independent variable (x).

Front

How do you write an equation from a word problem involving a fixed cost and a variable cost?

Back

Identify the fixed cost (y-intercept) and the variable cost per unit (slope), then use the form y = mx + b.

Front

What is the equation for the total cost if Frodo pays $14 to join and $2 for each event?

Back

Front

How can you identify the fixed cost in a word problem?

Back

The fixed cost is the amount that does not change regardless of the number of units or events.

Front

What does the variable 'x' typically represent in slope-intercept problems?

Back

The variable 'x' usually represents the independent variable, such as the number of trips, hours, or events.

Front

In the equation y = x + 18, what does the '1' represent?

Back
