I think that it’s A, Perpendicular (correct me if I’m wrong)
Answer: x=55 y=145
x=55
35+90=125
125-180=55
y=145
180-35=145
I hope this is good enough:
Part A: c for cost. c=0.31m+0.5
0.31m is the cost per minute. 0.5 is cost per call.
Part B: 0.31m+0.5=5.15 to solve we must rearrange.
subtract 0.5 from each side giving us 0.31m=4.85
divide by 0.31 giving us m=15.65
Its A because the vertical line is the y-axis so 4+-6 is -2 and the x-axis would remain the same. <span>#TeamAlvaxic</span>
I think the answer is d. The slope of AC=Slope of DF.
Hope this helped☺☺
