To find the slope of a line that passes through two points $(x_{1}, y_{1})$ and $(x_{2}, y_{2})$ , you use the formula:

$m = x ^{2} - x ^{1} y ^{2} - y ^{1}$

Given the points $(1, 2)$ and $(3, 6)$ :

$m = 3 - 1 6 - 2$ $m = 2 4$ $m = 2$

So, the slope of the line that passes through the points $(1, 2)$ and $(3, 6)$ is $2$

#9. What is the quadratic formula?

x = (-b ± √(b²-4ab)) / 2c

x = (-a ± √(a²-4bc)) / 2b

x = (-b ± √(b²-4ac)) / 2a

x = (-b ± √(b²-2ac)) / 2a
