Stella, roberto and candace are putting together small model kits. stella can put a kit together in 45 minutes, while it takes roberto 36 minutes. when all three of them work together, they can complete a kit in 12 minutes. which equation can be used to calculate how long it will take candace to put a kit together if she works alone?

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)

x:       y:  

-1         4

0         4

1         6

2         18

3         20
