Slope and Y-intercept

Front

What is the slope 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 represent in the equation y = mx + b?

Back

The y-intercept (b) is the point where the line crosses the y-axis, represented as (0, b).

Front

Determine the slope from the equation y = 3/2x + 3.

Back

The slope is 3/2.

Front

Identify the y-intercept from the equation y = 3/2x + 3.

Back

The y-intercept is (0, 3).

Front

How do you find the slope from a table of values?

Back

Calculate the change in y divided by the change in x (rise/run).

Front

What is the formula to calculate slope between two points (x1, y1) and (x2, y2)?

Back

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

Front

What is the y-intercept of the equation y = 2x + 5?

Back

The y-intercept is 5.

Front

If a line has a slope of -4/1, what does this indicate about the line?

Back

The line is decreasing, moving downwards from left to right.

Front

What is the slope of a horizontal line?

Back

The slope of a horizontal line is 0.

Front

What is the slope of a vertical line?

Back

The slope of a vertical line is undefined.
