Slope & Slope-Intercept Form

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 slope represent in a linear equation?

Back

The slope indicates how steep the line is and the direction it goes (positive or negative).

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

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

Back

The slope (m) is calculated as m = (y2 - y1) / (x2 - x1).

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

What does the y-intercept represent in a linear equation?

Back

The y-intercept (b) is the point where the line crosses the y-axis.

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 equation of a line with a slope of -3 and a y-intercept of 4?

Back

The equation is y = -3x + 4.

Front

How do you convert the equation y = 2x + 3 to slope-intercept form?

Back

It is already in slope-intercept form: y = mx + b.
