When you are multiplying exponents with the same base, you can add the exponents. This is represented as:

x^a \cdot x^b = x^{(a +b)}


In our case we are multiplying exponents with the same base 8 and exponents -7 and 5. The sum of -7 and 5 is -2, so our answer is \boxed{8^{-2}}.

Help please !! Thank u
leonid [27]

Answer:

parallel = same slope (-2x)

so it's y=-2x + b

let's find b by plugging in 1 for x and 3 for y (the coordinates)

3 = -2*1 + b

3 = -2 + b

5 = b

there you have it:

y = -2x +5

brainliest would really be appropriated (possible when someone else also leaves an answer)
