Answer:
y = x - 6
Step-by-step explanation:
The slope of y = -x is -1, so the slope of any line perpendicular to y = -x is +1. Thus,
y = mx + b becomes 2 = 1(8) + b, so that b = -6.
The desired equation is y = x - 6.
Check: Does (8,2) lie on this line? Is 2 = 8 - 6 true? YES.
Answer:
3. Look at the least amount of time practicing. That is 1/4 hours. Then look at the most time practicing, an hour and a half. Subtract 1 1/2 by 1/4.
4. Look at the dots in the plot. The one in the middle is the highest because it appears the most. The most common time is 3/4 of an hour.
5. To see the total time, add all of the numbers up, including the repeated ones.
Answer:
(2,1)
Step-by-step explanation:
This is the answer by substitution.
change 2x+y=5 to y=5-2x
5x-2(5-2x)=8
x = 2
y=5-2(2)
y = 1
(x,y) = (2,1)
You're welcome!!!
