Question

Find the slope of the line through each pair (1,-19),(-2,-7)

Answer 1

Answer: -4

Step-by-step explanation:

Use the slope formula (y2 - y1)/ (x2 - x1) where y2 is the second coordinates y output minus the first coordinates y output and the same for the x inputs

1. Plug the coordinates into the slope formula

(-7 -(-19))/ (-2 - 1)

2. Solve

12/-3

3. Simplify if possible

-4

Answer 2

hello i see that no one has answered your question yet well im here to help:)

(1,-19),(-2,-7)

so here one way you can find the slope

i usually always use this to help me to keep it in order

------------------

(X1,Y1)(X2,Y2)

   X2-X1

   Y2-Y1

use this and your garanteed to get the right answer everytime

------------------

X = -2 – 1 = -3

Y = -7 – -19 = 12

once you do that you divide if possible

12/-3

which gives you -4

so your answer is -4

its really not hard you just got to get use to it

hope it help you:)
