Graphing Lines

Front

What is the slope of the equation y = -2x - 1?

Back

-2

Front

Find the slope of the line using rise/run. If the rise is -5 and the run is 4, what is the slope?

Back

-5/4

Front

Describe the slope of a line that rises from left to right.

Back

positive slope

Front

Find the slope using rise/run. If the rise is -5 and the run is 3, what is the slope?

Back

-5/3

Front

Which of these is in slope-intercept form? y = mx + b, Ax + By = C, y2 - y1/x2 - x1, a + b = c

Back

y = mx + b

Front

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

Back

The slope of the line.

Front

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

Back

The y-intercept of the line.

Front

If a line has a slope of 0, what does it look like on a graph?

Back

It is a horizontal line.

Front

If a line has an undefined slope, what does it look like on a graph?

Back

It is a vertical line.

Front

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

Back

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