UEPB PB) A média aritmética das alturas de cinco edifícios é de 85 metros. Se for acrescentado a apenas um dos edifícios mais um andar de 3 metros de altura, a média entre eles passará a ser: a) 85,6 m b) 86 m c) 85,5 m d) 86,6 m e) 86,5 m

Step-by-step explanation:

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)

dude thats to long figure it
