Slope Intercept Form Review

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

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

Back

In the slope-intercept form, 'm' represents the slope of the line.

Front

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

Back

In the slope-intercept form, 'b' represents the y-intercept of the line.

Front

How do you find the slope from two points (x1, y1) and (x2, y2)?

Back

The slope (m) can be calculated using the formula m = (y2 - y1) / (x2 - x1).

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.

Front

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

Back

A slope of 2 means that for every 1 unit increase in x, y increases by 2 units.

Front

Write the equation of a line with a slope of -1 and a y-intercept of 3.

Back

The equation is y = -1x + 3 or y = -x + 3.

Front

What is the y-intercept of the line represented by the equation y = 4x - 5?

Back

The y-intercept is -5.

Front

How can you determine if a line is increasing or decreasing from its slope?

Back

If the slope (m) is positive, the line is increasing; if the slope is negative, the line is decreasing.
