Answer:

-4

Step-by-step explanation:

In order to get from point -1, 8, to point 2, -4, you would have to go down 12 and right 3, which would be 12/-3, which would simplify to -4

Answer:

<h2>-4</h2>

Option B is the correct option

Step-by-step explanation:

Let the points be A and B

A ( -1 , 8 ) -----> ( x1 , y1 )

B ( 2 , -4 ) -----> ( x2 , y2 )

Now, let's find the slope of the line:

\frac{y2 - y1}{x2 - x1}

plug the values

=  \frac{ - 4 - 8}{2 - ( - 1)}

Calculate the difference

\frac{ - 12}{2 - ( - 1)}

When there is a (-) in front of an expression in parentheses , change the sign of each term in expression

\frac{ - 12}{2 + 1}

Add the numbers

=  \frac{ - 12}{3}

Reduce the fraction with 3

=  - 4

Hope this helps..

Best regards!!

Find the slope.<br> (if it's a fraction with a whole number, write it as an improper fraction)
tiny-mole [99]

As you can see, every time x increases by 2, y decreases by 5.

So, we have

m=\dfrac{\Delta y}{\Delta x}=\dfrac{-5}{2}=-2\dfrac{1}{2}

Someone explain to me what y=mx+b please
antoniya [11.8K]
Y=mx+b is The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept. The y-intercept of this line is the value of y at the point where the line crosses the y axis.

Help this is really hars
s344n2d4d5 [400]
We have to find the slope of the line that passes through this points:
p1(-2,15), p2(-8,-5)
the slope of a line through two points is calculated like this:
m = (y2 - y1)/(x2 - x1)
where x1,y1,x2,y2 are the coordinates of the two points, so we have:
m = (-5 - 15)/(-8 - (-2))
m = (-20)/(-8 + 2)
m = -20/-6
m = 10/3
that is the line slope
