Question

find the slope of the line through each pair of points (Please show your work!)

(8,10), (-7,14)
(-3,1), (-17,2)
(-20,-4) , (-12, -10)
(-12, -5), (0,-8)
(-19, -6), (15,16)
(-6,9), (7,-9)
(-18, -20), (-18, 15)
(12, -18), (11,12)

Answer 1

Zelando,
formula for slope is
\[m=\frac{y_2-y_1}{x_2-x_1}\]

use this formula and get the result.

if you face some problem ask for help. This is not good habbit to get direct help for all the homework

Answer 2

u are given 2 points like P1(x1/y1) and P2(x2/y2)
all u have to do is: slope = (y2-y1) / (x2-x1)

for example: (14-10)/(-7-8)

Answer 3

so i for y1 and y2 i'd subtract them so i know what to divide by?
