Parallel lines have slopes that are equal to one another.
Slope intercept form is:
y = mx + b (where m = slope and b = y-intercept)
the equation of the 1st line
y = 3x + 4 so it’s slope (m) = 3
the problem tells us the y-intercept of the second line is -6.
so we plug the two knowns into slope intercept form to get the equation of the second line:
y = 3x - 6
I hope this helps and is the BRAINLIEST!
Great luck with your studies :)

Answer:
(1/2, 5)
Step-by-step explanation:
8x + 7y = 39
-2(4x - 14y = -68)
-8x + 28y = 136
8x + 7y = 39
add the two equations together
35y = 175
y = 5
8x + 7(5) = 39
8x = 4
x = 1/2
The period is found in one full cycle of the function. One "up-down-up", if you will. Our function starts below the x axis, so one full cycle goes from down to up to back down to back up. This up-down-up is complete at 3pi. So your answer is the third choice down.
Answer: The amount he earns from lifeguarding = $252 ($18×14). The total amount he needs to make a week is $270.
$270-$252=$18, he needs to earn $18 more from clearing tables.
$18÷9=2, so the minimum number of whole hours clearing tables is 2
