Maria has a 45-minute lunch break. During the break, she will walk 5 minutes to another floor, say “hello” to 5 different friends, spend equal time with each friend, and then taking 5 minutes to walk back to her desk. How long can she spend with each friend?

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)
