finding slope from a graph

What does an undefined slope indicate?

• A horizontal line where the rise is 0.

• A vertical line where the run is 0, leading to division by zero.

• A line with a positive slope that increases indefinitely.

• A line with a negative slope that decreases indefinitely.

What is the slope of a line?

• A measure of its length

• A measure of its steepness, usually represented as 'm'

• The angle it makes with the x-axis

• The distance between two points on the line

How do you find the slope from a graph?

• Select two points on the line and divide the run by the rise.

• Select two points on the line, determine the rise and run, and then divide the rise by the run.

• Draw a horizontal line and measure the distance between the points.

• Count the number of points on the line and divide by the total length.

If a line has a slope of -3/4, what does this tell you about its steepness?

• A slope of -3/4 indicates that for every 4 units you move to the right, the line goes down 3 units, making it steep and descending.

• A slope of -3/4 means the line is horizontal and does not change in height.

• A slope of -3/4 indicates that for every 3 units you move to the right, the line goes down 4 units, making it less steep.

• A slope of -3/4 suggests that the line is vertical and very steep.

If a line has a slope of 1/2, what does this mean in terms of rise and run?

• For every 1 unit you move to the right (run), the line rises 2 units (rise).

• For every 2 units you move to the right (run), the line rises 1 unit (rise).

• For every 1 unit you move to the right (run), the line rises 1 unit (rise).

• For every 3 units you move to the right (run), the line rises 1 unit (rise).

Calculate the slope between the points (1, 2) and (1, 5).

• The slope is 3.

• The slope is 0.

• The slope is undefined, as the x-coordinates are the same, leading to division by zero.

• The slope is 1.

What does a slope of 0 indicate?

• A slope of 0 indicates a vertical line, meaning there is no horizontal change as you move along the line.

• A slope of 0 indicates a horizontal line, meaning there is no vertical change as you move along the line.

• A slope of 0 indicates an increasing line, meaning the line rises as you move along it.

• A slope of 0 indicates a decreasing line, meaning the line falls as you move along it.
