y = mx + b

Front

What does the equation y = mx + b represent?

Back

It represents the slope-intercept form of a linear equation, where m is the slope and b is the y-intercept.

Front

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

Back

The slope (m) is 2.

Front

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

Back

The y-intercept (b) is 3.

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 the line rises as it moves from left to right.

Front

What does a negative slope indicate about a line?

Back

A negative slope indicates that the line falls as it moves from left to right.

Front

What is an undefined slope?

Back

An undefined slope occurs in a vertical line where the change in x is zero.

Front

What is the slope of the line represented by the equation y = 5x + 5?

Back

The slope (m) is 5.

Front

Which equation has a slope of 3?

Back

y = 3x + 5.

Front

If the slope is 0, what does the line look like?

Back

The line is horizontal.
