Mrs. Adam measured the performance times of middle school orchestra 10 points concerts and found a normal distribution. The mean concert time was 48
minutes with a standard deviation of 5.9 minutes. What percentage of
performances last more than 40 minutes? *

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)
