Answer:
y = -3x + 8.3
Step-by-step explanation:
You need to rearrange 9x + 3y = 22 in the form y = mx +c.
9x+3y = 22
3y = -9x +22
y = -3x + 7.3
As long as the gradient is the same, the lines will be parallel. So you can give any number to the intercept (in this case I gave 8.3) and you will have parallel equations.

Answer:
12 minutes
Step-by-step explanation:
Let us suppose the number of minutes per month is 720. ( i have assumed this data from my self, you use any data you want, remember the procedure)
Now , Mark and his brother share the minutes every month equally.
So, clearly, Mark and his brother would get 360 minutes each every month.
Now, Mark has 360 minutes each month
therefore, Mark has 360/30 minutes per day
= 12 minutes each day.
