Answer:
see attached image for the graph
Step-by-step explanation:
To graph the linear equation :
![y=\frac{3}{4} x+2](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B3%7D%7B4%7D%20x%2B2)
we need just two points
pairs, but we better use three to make sure they are aligned. We can find convenient pairs by choosing values of the x-variable that are multiples of 4 in order to cancel the denominator of the slope
: So let's use:
1) x=0 then
giving the pair: (0,2)
2) x=4 then
giving the pair: (4,5)
3) x=-4 then
giving the pair: (-4,-1)
Now we plot then on the grid (see attached image) and join them with a straight line.
It took Andre and Lin 1.5 hours for them to meet.
Speed is the ratio of distance travelled to total time taken. Speed is given by:
Speed = distance/time
Let d₁ represent the distance covered by Andre at time t and d₂ represent the distance covered by Lin at time t.
Hence:
5 = d₁/t
d₁ = 5t
3 = d₂/t
d₂ = 3t
Andre and Lin are 12 miles apart, hence:
d₁ + d₂ = 12
5t + 3t = 12
8t = 12
t = 1.5 hours
It took Andre and Lin 1.5 hours for them to meet.

Answer:
6 Gallons of Paint
Step-by-step explanation:
If you use a half gallon of paint to cover 84 square feet, how much could you paint with a full gallon? Lets figure it out:
![\frac{1}{2} = 84](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20%3D%2084)
multiply both sides by 2 so that the 1/2 gallon is now 1 gallon:
![\frac{1}{2} * 2 = 84 * 2](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B2%7D%20%2A%202%20%3D%2084%20%2A%202)
1 gallon = 168 square feet
now, how many gallons does it take to paint 932 square feet?
Divide 932 by 168:
![\frac{932}{168} = 5.548](https://tex.z-dn.net/?f=%5Cfrac%7B932%7D%7B168%7D%20%3D%205.548)
Just like you cant buy 2.374 cheeseburgers, you cant buy 5.548 gallons of something so we round up and will have some paint left over once the job is done. So 6 gallons is the answer
