Answer:

Line JK passes through points J(-4,-5) and K(-6, 3).

Line JK has form of y = mx + b

=> -5 = -4m + b

=>  3 = -6m + b

Subtract 2nd equation from 1st equation:

=> -8 = 2m

=> m = -4

Substitute back m = -4 into 1st equation:

=> -5 = -4(-4) + b

=> b = -21

Hope this helps!

:)

I need help on #10. very confused
RideAnS [48]

Step-by-step explanation:

\displaystyle f'(x) = \lim_{h \to 0} \dfrac{f(x + h) - f(x)}{h}

\:\:\:\:\:\displaystyle = \lim_{h \to 0} \dfrac{(x+h)^2 -7 -(x^2 - 7)}{h}

\:\:\:\:\: \displaystyle= \lim_{h \to 0} \dfrac{(x^2 +2hx + h^2 -7) - (x^2 -7)}{h}

\:\:\:\:\: \displaystyle= \lim_{h \to 0} \dfrac{2hx + h^2}{h}

\:\:\:\:\: \displaystyle= \lim_{h \to 0} (2x +h)

\:\:\:\:\: \displaystyle= 2x
