Question

How do you find the slope of a linear equation with only the numbers they give you?

Answer 1

Hello!

In order to find the slope of a linear equation, you need two ordered pairs from the graph.

Once you have the two ordered pairs, you use the slope formula to find the slope. The formula is:
`(y_(2)-y_(1))/(x_(2)-x_(1))`.

With that formula, you assign the ordered pairs to
`y_(2)`,
`y_(1)`,
`x_(2)`, and
`x_(1)`.

Note that
`x_(1)` and
`y_(1)` must be assigned to one of the ordered pairs.
`x_(2)` and
`y_(2)` is assigned to the other ordered pair.

Then, you substitute the assigned ordered pairs into the formula and solve for the slope.
