y = mx + b

Front

What is the equation of a straight line in slope-intercept form?

Back

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

Front

What does the slope (m) represent in the equation y = mx + b?

Back

The slope (m) represents the rate of change of y with respect to x.

Front

What does the y-intercept (b) represent in the equation y = mx + b?

Back

The y-intercept (b) is the value of y when x = 0.

Front

What is the ordered pair for the origin on a coordinate plane?

Back

(0, 0)

Front

How do you determine if a table of values has a constant rate of change?

Back

If the difference in y-values divided by the difference in x-values is the same for all intervals, it has a constant rate of change.

Front

If a line has a slope of 2, what does this mean?

Back

For every 1 unit increase in x, y increases by 2 units.

Front

What is the rate of change if a line rises 40 units over a run of 20 units?

Back

The rate of change is 2 (40/20 = 2).

Front

How can you find the slope of a line given two points (x1, y1) and (x2, y2)?

Back

Slope (m) = (y2 - y1) / (x2 - x1).

Front

What is the slope of a line that goes down from left to right?

Back

The slope is negative.

Front

What is the slope of a line that goes up from left to right?

Back

The slope is positive.
