What is the slope of the line that passes through (-4,6) and (-6,20)

san4es73 [151]

Answer:

<h2>The answer is - 7</h2>

Step-by-step explanation:

The slope of a line given two points can be found by using the formula

$m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\$

where

(x1 , y1) and (x2 , y2) are the points

So the slope is

$m = \frac{20 - 6}{ - 6 - - 4} = \frac{14}{ - 6 + 4} = - \frac{14}{2} = - 7 \\$

We have the final answer as

Hope this helps you

White raven [17]

Answer:

-3 and 17

Step-by-step explanation:

Let the number be = x

x - 7 = -10

x = -10 + 7

x = -3

7 - x = -10

- x = -10 - 7

- x = -17

x = -17/-1

x = 17

The two possible numbers are -3 and 17
