unit 3: parallel & perpendicular lines homework 6: slope-intercept form & standard form determine if the equations are p
1 answer:
Answer:
Step-by-step explanation:
Eq. 1: y=-3x+6
Eq. 2: y=1/3 x-8
-----
Form: y = mx + b, where m is the slope and b the y-intercept.
Parallel lines have identical slopes. Perpendicular lines have slopes that are the negative inverse of each other.
<u>Line</u> <u>Slope</u>
1 -3
2 (1/3)
(1/3) is the negative inverse of -3, so these lines are perpendicular.

Answer:
Yes, he earned a Varsity letter because he played in 61% of the games.
Step-by-step explanation:
To know the percent of games he played out of the total, we can do it by dividing the games he played by the total of games and multiply this by 100% to get the percent of games he played:
We solve:
0.611111*100% = 61.11%
So we know that he earned a letter because he played in 61.11% of the games, more than he needed.
