For the equation of the line expressed as Ax + By + C = 0, the value of the slope (m) is calculated by -A / B. For perpendicular lines, the slope of one should be the negative reciprocal of the other. From the choices given, the lines that are perpendicular is Option A.

Dan had 15 cups<br> Of apple juice he wanted to add 6 oz how much would he have in the end?
yaroslaw [1]
If you want to know the total, it would be 15 cups and 6 oz. One cup is 8 oz, so 6 oz would have to stand next to 15 cups. 
If  you want to know the total amount of ounces, it would be 126 ounces. 
This information is only accurate if you are using USA  measurements. 
Hope this helps! Have a happy holiday!
