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!

If (x-2) is a factor of x^3+kx^2 +12x-8 then k=?
AURORKA [14]

Answer:

k = - 6

Step-by-step explanation:

Since (x - 2) is a factor then x = 2 is a root

Substitute x = 2 into the polynomial and equate to zero, that is

2³ + k(2)² + 12(2) - 8 = 0

8 + 4k + 24 - 8 = 0

4k + 24 = 0 ( subtract 24 from both sides )

4k = - 24 ( divide both sides by 4 )

k = - 6
