Fin find the slope of the line passing through the points (-2, -7) and (9, -7)

Verdich [7]

Answer:

The slope of the line passing through the given points (-2,-7) and (9,-7) is m=0

Step-by-step explanation:

Given that the line passing through the points (-2,-7) and (9,-7)

To find the slope of the line passing through the points :

$m=\frac{y_2-y_1}{x_2-x_1}$

Let $(x_1,y_1)$ and $(x_2,y_2)$ be the given points (-2,-7) and (9,-7) respectively

Substitute the points in the formula $m=\frac{y_2-y_1}{x_2-x_1}$

$m=\frac{-7-(-7)}{9-(-2)}$

$=\frac{-7+7}{9+2}$

$=\frac{0}{11}$

Therefore m=0

Therefore Slope m is 0

Therefore the slope of the line passing through the given points (-2,-7) and (9,-7) is m=0

I need help on this asap please. <br> im being timed.<br> and i put in a photo of the problem.

$F=ma\\\\a.\\ma=F\qquad|\text{divide both sides by}\ a\neq0\\\\m=\dfrac{F}{a}\\\\b.\\F=-30,\ a=6.\ \text{Substitute}\\\\m=\dfrac{-30}{6}=-5\\\\c.\\ma=F\qquad|\text{divide both sides by}\ m\neq0\\\\a=\dfrac{F}{m}\\\\F=30,\ m=10.\text{Substitute}\\\\a=\dfrac{30}{10}=3$

96 16 81 = x 11 15 18 = y what is the value of y-2x?

qwelly [4]

Hey, im not really sure but i think it is that 1. x=96 y=11 2. x=16 y=15 3.x=81 y=18
Then you just substitute the numbers into the letters. For example,

11-96(2)= -181

15-16(2)= -17

18-81(2)= -144
