Every integer is a rational number.
True or false

Every integer is a rational number. The statement is true. An integer is a number with no decimal or fractional part, from the set of negative and positive numbers, including zero.

For example, lets use the integer, -5.

If it was rational number it would need to be either a decimal or fraction.

So -5 is not a rational number and is an integer.

If the number was 0.5 or 1/5, the number would have been rational.

Inconclusion your statement is true.

he spend 5.1 minutes chatting with his friends.

step-by-step explanation:

2/5+1/2=9/10

6/1-9/10=5.1

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)
