The formula for the slope m

Question

The formula for the slope m of the line containing the points P₁(1, 4) and P₂(−2, −1) is given below. Find the slope.



Answer 1

In case you have like problems, it’s easy to use the slope formula. Good formula to know!

To refresh your memory, that’s rise/run. Slope =𝑦2−𝑦1/𝑥2−𝑥1.

So you are given the variable in numeric form. So you have two negatives, that will convert to the positive for the slope.

-1-4= ? numerator =𝑦2−𝑦1

-2-1= ? denominator (𝑥2−𝑥1.)
