Front

What is the slope of the line represented by the equation y = 2/3x - 3?

Back

2/3

Front

What is the y-intercept in the equation y = -2x + 4?

Front

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

Back

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

Front

What is the standard form of a linear equation?

Back

Ax + By = C, where A, B, and C are constants.

Front

What does the term 'y-intercept' refer to?

Back

The point where the line crosses the y-axis (x=0).

Front

What is the slope of a horizontal line?

Back

0.

Front

What is the slope of a vertical line?

Back

Undefined.

Front

If a line has a slope of -3, what does this indicate about the line's direction?

Back

The line descends from left to right.

Front

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

Back
