5:7 (pencils to pens)
7/12 chance that a pen from the first box will be selected.
4:4 (colour pencils to crayons)
4/8 = 1/2 chance that a crayon from the second box will be selected.
The probability of picking both:
7/12 * 1/2 = 8/24 = 1/3

To divide like bases just subtract the exponents
answer is 2^(13-3) or 2^10 or 1024

Answer:
y = -x
Step-by-step explanation:
The line has a slope of -1 and it passes through point (0,0)
Taking another point (x,y) on the line;
Slope = change in y ÷ change in x
For our case; slope = 
Cross multiplying this gives;
y = -x
