Answer:
For the 12 sided one it would be 1/12
For the 6 sided one it would be 1/6
Combine those together and it would be <u>3/12</u> which is equal to <u>1/4</u>
Step-by-step explanation:
First, you have to find the equation of the perpendicular bisector of this given line.
to do that, you need the slope of the perpendicular line and one point.
Step 1: find the slope of the given line segment. We have the two end points (10, 15) and (-20, 5), so the slope is m=(15-5)/(10-(-20))=1/3
the slope of the perpendicular line is the negative reciprocal of the slope of the given line, m=-3/1=-3
step 2: find the middle point: x=(-20+10)/2=-5, y=(15+5)/2=10 (-5, 10)
so the equation of the perpendicular line in point-slope form is (y-10)=-3(x+5)
now plug in all the given coordinates to the equation to see which pair fits:
(-8, 19): 19-10=9, -3(-8+5)=9, so yes, (-8, 19) is on the perpendicular line.
try the other pairs, you will find that (1,-8) and (-5, 10) fit the equation too. (-5,10) happens to be the midpoint.
Answer:
y = -3x - 1
Step-by-step explanation:
Look at your line. It's a downward trend which means your slope is negative
slope is the m in y = mx+b
Your b is your y intercept or where the graph touches the y = 0 vertical line.
It cross at -1 value
Your slope value is determined by rise/run so in the case it goes down 3 values and across 1 value so its 3/1 but its negative so its -3/1
