First calculate the slope by change in y over change in x
it’s -0.334
then find y intercept
-6
so all together
-0.334x-6

thanks so much for the points
3(x + 8) = 17....distribute the 3 thru the parenthesis
3x + 24 = 17...subtract 24 from both sides
3x = 17 - 24
3x = -7...divide both sides by 3
x = -7/3 or -2 1/3 <===
Answer:
Step-by-step explanation:
Given
Rate of Long family's sprinkler is 25 L/hr
rate of Harris family's sprinkler is 35 L/hr
Total time for which sprinkler is used =55 hr
Let long family run their sprinkler for x hr
therefore Harris family time=55-x
Total volume collected=1625 L
thus

25x+1925-35x=1625
1925-1625=10x
300=10x
x=30 hr
long family used for 30 hr and Harris family used for 20 hr
