Answer:

The slope is -2.

Step-by-step explanation:

The slope formula is ⇒ $\displaystyle \frac{y_2-y_1}{x_2-x_1}$

$\displaystyle \frac{(-4)-8}{5-(-1)}=\frac{-12}{6}=\frac{-12\div6}{6\div6}=\frac{-2}{1}=-2$

Therefore, the slope is 2, and the correct answer is 2.

so you just do the slope formula

which y2-y1 over x2-x1 in fraction form

so you would do

(-1 , 8) (5 , -4)

(x1 , y1) (x2 , y2)

-4 - 8 over 5- (-1)

which would give you the fraction 12/6

it can be simplified to 2

so 2 is your slope

hope it help

Answer:

(86.2,0) is the x-intercept.

Step-by-step explanation:

You can use the slope formula to figure this one out:

Just use two of the points on the table, any of them will work:

$(33,-22)\\(52,-33)$

$\frac{-22-33}{33-52} =\frac{-55}{-19}=\frac{55}{19}$

Now you have the slope of the equation, now using the y-intercept equation you can substitute the variables for point of the table and the new slope.:

$(71,-44)\\y=mx+b\\-44=\frac{55}{19} (71)+b$

Now just solve for b to get the y intercept:

$-44=\frac{55}{19}(71)+b\\-44= \frac{3905}{19} +b\\(-\frac{3905}{19})-44=\frac{3905}{19} +b(-\frac{3905}{19})\\ -\frac{4741}{19}=b$

Now you have the y-intercept so you just have to plug in 0 to the y spot and it will calculate the x-intercept.

$0=\frac{55}{19}x-\frac{4741}{19}\\(+\frac{4741}{19})0=\frac{55}{19}x-\frac{4741}{19}(+\frac{4741}{19})\\\\\frac{4741}{19}=\frac{55}{19}x\\\frac{\frac{4741}{19}}{\frac{55}{19} }= \frac{\frac{55}{19} x}{\frac{55}{19} } \\\frac{431}{5} =x\\or\\86.2=x$
