Evaluate: [(- 16) + 4] ÷ [(-2) + 5]

Tresset [83]

Answer:

We need to evaluate this: [(-16)+4] / [(-2)+5]

First, we do the brackets:

[(-16)+4]
[(-2)+5]

[(-16)+4] = -16 + 4 = -12

[(-2) + 5] = -2 + 5 = 3

Now, we only need to divide, as we have calculated both brackets:

-12/3 = -4

(Remember that when dividing a negative number by a positive one, we always obtain a negative)

So the result is -4

Use the slope formula to find the slope of the line through the points (2,10) and (10,−8).

Salsk061 [2.6K]

The slope formula is the changes of two y-values over/to the changes of two x-values.

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

Substitute two given points in the formula to find the slope. The m-term represents the slope from y = mx+b.

$\large{m = \frac{10 - ( - 8)}{2 - 10} } \\ \large{m = \frac{10 + 8}{ - 8} } \\ \large{ m = \frac{18} { - 8} \longrightarrow \frac{9}{ - 4} } \\ \large \boxed{m = - \frac{9}{4} }$

Answer

The slope is -9/4.

Hope this helps and let me know if you have any doubts!
