Find the slope of the line contain the given pair of points (-6,4) and (1,0)

EastWind [94]

$(-6,4) \\
x_1=-6 \\
y_1=4 \\ \\
(1,0) \\
x_2=1 \\
y_2=0 \\ \\
\hbox{the slope}=\frac{y_2-y_1}{x_2-x_1}=\frac{0-4}{1-(-6)}=\frac{-4}{1+6}=-\frac{4}{7}$

The slope is -4/7.

What is the solution to the inequality -6+|2p+3|>7

andrezito [222]

Answer:

p >5 or p <-8

Step-by-step explanation:

-6+|2p+3|>7

Add 6 to each side

-6+6+|2p+3|>7+6

|2p+3|>13

We get a positive and negative solution

2p +3 > 13 and 2p +3 < -13

Subtract 3 from each side

2p +3 -3> 13-3 or 2p +3-3 < -13-3

2p > 10 2p < -16

Divide by 2

2p/2 > 10/2 2p/2 <-16/2

p >5 or p <-8
