Hannah says all integers are rational. Is Hannah correct?

Hannah is correct.

Step-by-step explanation:

A rational number is a number that can be written as the quotient of two integer numbers.

This means that if we have an integer a, and an integer b, then:

a/b is a rational number.

In the particular case where b = 1 we have:

a/1 = a

This means that a is also a rational number.

And a can be any integer, then we can conclude that all the integer numbers are also rational numbers.

So Hannah is correct.

step-by-step explanation:

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
