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 = mx + b?

Back

The slope (m) indicates the steepness and direction of the line on a graph.

Front

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

Back

The y-intercept (b) is the point where the line crosses the y-axis.

Front

If m = 2 and b = 3, what is the equation of the line?

Back

y = 2x + 3

Front

How do you find the y-intercept from a graph?

Back

Locate the point where the line crosses the y-axis.

Front

What does a positive slope indicate about a line?

Back

A positive slope indicates that the line rises from left to right.

Front

What does a negative slope indicate about a line?

Back

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

Front

If the slope m = 0, what does the line look like?

Back

The line is horizontal, indicating no change in y as x changes.

Front

If the slope m is undefined, what does the line look like?

Back

The line is vertical, indicating that x is constant regardless of y.

Front

What is the equation of a line with a slope of -1 and a y-intercept of 4?

Back

y = -1x + 4 or y = -x + 4
