Ireally really need on this question what is the answer for this ( how much would it cost to mail a letter that weighs 2.7ounces? )

It costs $.50 to mail a letter of that size.

All letters that are under 3.5 oz take only one stamp to ship. Since 2.7 is less, it would cost only $.50

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)
