Answer: y= x/5 -6
Step-by-step explanation: gradient= 1/5...(m1m2=-1)
y-y1=M(x-x1)
y-8=1/5(x-10)
5y-40=x-10
y=x/5-6
You would need to add 360L of the 20% ethanol solution.
Answer:
y=x+8
Step-by-step explanation:
y=x+b
That is the equation with only the slope, however, we can use the point (-4,4) to find the y-intercept
4=-4+b
Add 4 both sides:
8=b
Thus the equation is y=x+8
Hope this helps!
