12/4 Slope Intercept Form Review

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

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

Back

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

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that as x increases, y also increases.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that as x increases, y decreases.

Front

What is the slope of the line represented by the equation y = 4x + 1?

Back

The slope is 4.

Front

What is the y-intercept in the equation y = mx + b?

Back

The y-intercept (b) is the value of y when x = 0.

Front

How can you determine the slope from a table of values?

Back

Calculate the change in y divided by the change in x between two points.

Front

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

Back

The slope is -3.

Front

What does the equation y = 0 represent?

Back

It represents a horizontal line with a slope of 0.

Front

What does the equation x = 5 represent?

Back

It represents a vertical line where x is always 5, with an undefined slope.
