Slope Intercept From- Word Problems

Front

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

Back

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

Front

In the equation y = mx + b, what does 'b' represent?

Back

'b' represents the y-intercept, which is the point where the line crosses the y-axis.

Front

How do you identify the slope from a word problem?

Back

The slope represents the rate of change and can be identified by the change in the dependent variable per unit change in the independent variable.

Back

y = -2000x + 30000.

Front

What does 'm' represent in the slope-intercept form y = mx + b?

Back

'm' represents the slope of the line.

Front

How do you convert a word problem into a slope-intercept equation?

Back

Identify the fixed cost (y-intercept) and the variable cost (slope) based on the problem.

Front

What is an example of a fixed cost in a slope-intercept equation?

Back

A fixed cost is a constant amount that does not change, such as $25 for a service call.
