A scientist mixes water (containing no salt) with a solution that contains 40% salt. She wants to obtain 240 ounces of a mixture that is 5% salt. How many ounces of water and how many ounces of the 40% salt solution should she use. Water: ___ ounces

Salt solution: ___ ounces

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

multiply then divide
