Answer: 3 people ordered soup.
Step-by-step explanation:
Let x be the number of people ordered salad and y be the number of people ordered soup.
As per given,
x=2y (i)
7.50x+6.25y= 63.75 (ii)
Substitute value of c =2y in (ii) , we get
7.50(2y)+6.25y= 63.75
⇒ 15y+6.25y = 63.75
⇒21.25y = 63.75
⇒ y= 3 [divide both sides by 21.25]
Then, x= 2(3) =6
So 6 people ordered salad and 3 people ordered soup.

Answer: y = 3x+10
------------------------------------------------------------------------------------
Explanation:
The line y = 3x+11 is in slope intercept form y = mx+b where m = 3 is the slope. Anything parallel to this line will also have a slope of 3. Let's plug in m = 3 and (x,y) = (-2,4) which is the point this parallel line goes through.
y = mx+b
y = 3x+b ... replace m with 3
4 = 3(-2)+b ... replace x with -2; replace y with 4
4 = -6+b
4+6 = -6+b+6 ... add 6 to both sides
10 = b
b = 10
Since m = 3 and b = 10, this means that y = mx+b turns into y = 3x+10
