The slope, m, of a linear equation can be found using the formula <img src="https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7By_2%20-%
Svetradugi [14.3K]

Answer:

Answer c: m(x2 - x1) + y1 = y2

Step-by-step explanation:

Hi there!

Let´s start writting the formula

m = \frac{y2 -y1}{x2-x1}

If we multiplicate both sides by (x₂ - x₁):

m(x2 - x1) = y2 - y1

Then if we add y₁ to both sides of the equation:

m(x2 - x1) + y1 = y2

Then, the right answer is the answer c)

Have a nice day!
