When a line is perpendicular to another line with a given slope, you can use the given slope of the original line to find the slope of the perpendicular line. All you need to do is flip the reciprocals. Since the slope of the given line is -1/8x, the slope of the perpendicular line would be 8x. Since there is only one line with a slope of 8x in the answer choices, your answer would be:
a. y=8x+13

Step-by-step explanation:
W+y=25 and 9.95w+11.5y=276.65
solve for w in equation one:
w+y=25
w=25-y
then substitute w in equation two and solve for y:
9.95w+11.5y=276.65
9.95(25-y)+11.5y=276.65
1.55y+248.75=276.65
1.55y+248.75-248.75=276.65-248.75
1.55y=27.9
1.55y/1.55=27.9/1.55
y=27.9/1.55=18
y=18
then substitute y=18 into the first equation to solve for x:
w+y=25
rewrite as w=25-y y=18
w=25-18
w=7
then are answer is w=7 and y=18
