Front

What is the slope in the equation y=2x + 3?

Back

The slope is 2.

Front

Write the equation 2x + y = 2 in slope-intercept form.

Back

The slope-intercept form is y = -2x + 2.

Front

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

Back

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

Front

What is the slope of the line that passes through the points (1, -19) and (-2, -7)?

Back

The slope is -4.

Front

What is the slope of a line if it rises 3 units for every 6 units it runs?

Back

The slope is 1/2.

Front

In the equation y = mx + b, what does 'm' represent?

Back

'm' represents the slope of the line.

Front

In the equation y = mx + b, what does 'b' represent?

Back

'b' represents the y-intercept of the line.

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 can you determine if two lines are parallel using their slopes?

Back

Two lines are parallel if they have the same slope.
