Find the slope of the line that passes through the points without graphing. (3,9) and (-5,3)

Answer 1

The slope formula is the change in y divided by the change in x.

This can be written as:

y₂-y₁/x₂-x₁

(3,9) and (-5,3) are your two points

We know that (3,9) Is the first point, or (x_1,y₁)

We know that (-5,3) is the second point, or (x_2,y₂)

We can then substitute the values in

3-9/-5-3

-6/-8

3/4

Answer 2

We can find the slope by taking the change over Y divided by the change over X, so it should be (3-9)/(-5-3), which simplifies to 3/4.
