16. In order to get a thicker sauce, a restaurant owner combines a sauce that is 70% tomato paste with the original sauce, which is 40% tomato paste.
How much of each should be used to make 5 L of the new 60% tomato
paste sauce?

based on context clues you gave i'm assuming the answer would be c.

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)
