6

Front

What does the slope represent in a linear equation?

Back

The slope represents the rate of change of y with respect to x.

Front

What is the standard form of a linear equation?

Back

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

Front

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

Back

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

Front

What is the slope of the line represented by the equation y = -¾x + 1?

Back

-¾

Front

What is the definition of a linear equation?

Back

Front

What is the x-intercept of a line?

Back

The point where the line crosses the x-axis.

Front

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

Back

2

Front

How do you graph the equation y = mx + b?

Back

Start at the y-intercept (b) and use the slope (m) to find another point.

Front

What does it mean if a line has a positive slope?

Back

As x increases, y also increases.
