Question

What is the slope for (20, 8), (9, 16) I got more if able to answer all
(19, 3) (20, 3)
(19, -2), (-11, 10)
??? Please help!!!

Answer 1

Slope of (20, 8), (9, 16) = 8/-11

Slope of (19, 3) (20, 3) =0

Slope of (19, -2), (-11, 10)= 2/-5

Further explanation:

The slope of two points is given by:

$m=\frac{y_2-y_1}{x_2-x_1}\\Here\\(x_1,y_1)\ are\ coordinates\ of\ first\ point\\(x_2,y_2)\ are\ coordinates\ of\ second\ point$

Now:

Slope of (20, 8), (9, 16):

$m=\frac{16-8}{9-20}\\=\frac{8}{-11}$

Slope of (19, 3) (20, 3):

$m=\frac{3-3}{20-19}\\ =\frac{0}{1} \\=0$

Slope of (19, -2), (-11, 10):

$m=\frac{10-(-2)}{-11-19} \\=\frac{10+2}{-30}\\ =\frac{12}{-30}\\ =\frac{2}{-5}$

Hence,

Slope of (20, 8), (9, 16) = 8/-11

Slope of (19, 3) (20, 3) =0

Slope of (19, -2), (-11, 10)= 2/-5
