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

Back

The slope of the line.

Front

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

Back

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

Front

How do you identify the slope from a word problem?

Back

Look for the rate of change or the amount that y changes for each unit change in x.

Front

In the equation y = 5x + 20, what does the number 20 represent?

Back

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

Front

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

Back

It represents the initial value or starting point before any changes occur.

Front

How can you convert a word problem into slope-intercept form?

Back

Identify the fixed costs (y-intercept) and the variable costs (slope) from the problem.

In the equation y = -2000x + 30000, what does the -2000 represent?

Back

The rate of descent of the airplane in feet per minute.

Front

What does it mean if the slope of a line is negative in a real-world scenario?

Back

It indicates a decrease in the value of y as x increases.

Front

How do you determine the total cost from a canoe rental problem?

Back

Add the fixed transportation fee to the variable cost per hour multiplied by the number of hours.
