Describe how you can tell whether a lines slope is greater than 1,equal to 1, or less than 1

From the equation of the line:-

Convert the line to the slope/intercept form

y = mx + b

m = slope  so this value will tell you what you want to know.

For example  y = x - 3 has a slope of 1

and y = 0.5x + 2 has a slope of less than 1.

You can determine by observing how the line slants on a graph, and also by using the slope formula given as

You can determine whether a slope of a line by observing the line on the graph as follows:

The slope of a line that passes through two points on a coordinate plane is the change in y over change in x.

Slope (m) can be calculated using the formula below:

See diagram below to showing the rise and run of a slope.
