Let the concentration of new vinegar solution is x%.
According to question, we will get
Therefore the new concentration of vinegar is 49.17% .
So if the line is linear we can use slope intercept form to find the equation of the points: y=mx+b
To calculate m, the slope we subtract two of the points (I’ll use the first two):
(-1, 1)
(4, 0)
This equals 0-1/4+1, which simplifies to -1/5
So the slope is -1/5 and we can put that into slope intercept form along with a point to get b, the y-intercept.
So, y=-1/5x+b
Now we substitute x and y with a point.
1=-1/5(-1)+b
1=1/5+b
b=4/5
So the equation is:
y=-1/5x+4/5
I hope this helps!
