Answer:

  4 oz of water must be evaporated

Step-by-step explanation:

If we let x represent the amount of water to be evaporated, the relation between the solutions is ...

  0.08 · 36 oz = 0.09 · (36 -x) oz

  0.09x = 36(0.09 -0.08) . . . . . divide by oz; add .09x, subtract .08·36

  x = 36· 0.01/0.09 = 36/9 = 4

4 ounces of water must be evaporated.

Y-2=4(x-1) use the point slope for each equation
melomori [17]

Slope = 4

Point = (1, 2)

<h2>Explanation:</h2>

Remember you need to post complete questions in order to get precise and good answers. However, I'll assume you need the point and slope of the following line:

y-2=4(x-1)

A line written in Point-Slope form is given by:

y-y_{0}=m(x-x_{0}) \\ \\ \\ Where: \\ \\ Slope:m=4 \\ \\ Point:(x_{0},y_{0})=(1,2)

By using tools, we get the graph in the figure below. As you can see, this line passes through (1, 2) and has a slope:

m=\frac{4}{1}=4
