Please help please please I’ll give brainly
gayaneshka [121]
To find the slope, we can use the formula m = y change/x change. Since we already have 2 points, we can subtract the second coordinates from the first ones.
1. (-18-(-18))/(15-6) = 0/9 = 0. m=0x
2. (16-12)/0-8) = 4/-8 = -1/2. m = -1/2x
Hope this helps.

Help me please! will mark brainliest for the correct answer
IceJOKER [234]

Answer:

see explanation

Step-by-step explanation:

Using the rules of exponents

a^{m} × a^{n} ⇔ a^{(m+n)}

(a^m)^{n} = a^{mn}

a^{-m} ⇔ \frac{1}{a^{m} }

Thus

4^{3x-2}

= 4^{3x} × 4^{-2}

= (4^3)^{x} × 4^{-2}

= 64^{x} × \frac{1}{4^2}

= \frac{64^{x} }{16} ← as required
