1. to which set of numbers does the number belong? –55 (1 point) natural numbers / whole numbers/ integers / irrational numbers

The number –55 is an integer.

Step-by-step explanation:

Consider the provided information.

Whole numbers are the numbers 0, 1, 2, 3, 4, 5,...

Natural numbers are the numbers 1, 2, 3, 4, 5,...

Integers are the whole numbers, but they include negative numbers ...-5,-4,-3,-2,-1,0,1,2,3,4,5..

Irrational numbers are numbers which are not expressible as a ratio of two integers.

Now consider the provided number –55.

From the above definition the number –55 is neither whole number nor the natural number. Also –55 is not an irrational number because it can be expressible as a ratio of two integers.

Hence, the number –55 is an integer.

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)

answer: it's a
