What exactly are we trying to work out here?
Answer:
Perpendicular.
Step-by-step explanation:
For parallel lines slopes are equal.
The slope of y = x + 3 is 1 and the slope of y = -x - 5 is -1 so they are not parallel.
For perpendicular lines m1*m2 = -1 (where m1 and m2 are the slopes).
So these 2 lines are perpendicular.
For this I used elimination
X=2
Y=0
Answer:
21
(2,14)
14/2=7
14+7=21
21 is final answer
Erika had a 95% chance of guessing wrong
20 can be seen as 100%
the % will go down by 5's because of the original number
.5*20=
This will give you a 95% success rate.
