Slope and Y-intercept from the GRAPH only

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, usually represented as 'm'. It is calculated as the change in y (rise) over the change in x (run).

Front

What does the y-intercept represent in a graph?

Back

The y-intercept is the point where the line crosses the y-axis, represented as 'b' in the equation y = mx + b.

Front

How do you find the slope from a graph?

Back

To find the slope from a graph, select two points on the line, calculate the rise (change in y) and run (change in x), and then divide rise by run.

Front

What is the slope of the line represented by the equation y = 3x + 5?

Back

The slope (m) is 3.

Front

What is the y-intercept of the line represented by the equation y = -2x + 4?

Back

The y-intercept (b) is 4.

Front

If a line has a slope of -1/2, what does this indicate about its direction?

Back

A slope of -1/2 indicates that the line descends from left to right.

Front

What does a slope of 0 indicate about a line?

Back

A slope of 0 indicates that the line is horizontal.

Front

What does an undefined slope indicate about a line?

Back

An undefined slope indicates that the line is vertical.

Front

How can you determine if a graph is proportional or non-proportional?

Back

A graph is proportional if it passes through the origin (0,0); otherwise, it is non-proportional.

Front

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

Back

The slope (m) is -4.
