Answer:

Step-by-step explanation:

(-2, y) lies on the graph of $y = 4^x$

It means for x=-2 we need to find the y =?

means we plug x=-2 in the given equation $y = 4 ^x$

so we get

$y = 4^ (-2)$

$y = \frac{1}{4^2}$

$y = \frac{1}{16}$

Answer:

(2,1)

Step-by-step explanation:

$\mathrm{Midpoint\:of\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\\\quad \left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)\\\\\left(x_1,\:y_1\right)=\left(-5,\:-2\right),\:\left(x_2,\:y_2\right)=\left(9,\:4\right)\\\\=\left(\frac{9-5}{2},\:\frac{4-2}{2}\right)\\\\= (\frac{4}{2} , \frac{2}{2} )\\\\=\left(2,\:1\right)$
