Any number that can be written as a ratio of two integers
adoni [48]

Answer:

Rational number

Step-by-step explanation:

Any number that can be written as a ratio of two integers is a rational number.

In the question, you have the keyword 'ratio', meaning a comparison between two numbers.  For example 1.5 can be expressed as the ratio between 3 and 2 (3/2), as a fraction.

<u>When a number cannot be expressed as a fraction, it's called an irrational </u>number. <u> The most famous irrational number of all would be pi (π). </u> You cannot express pi in a ratio between numbers, because it's  too complicated, it's basically an infinite number without any periodicity.

What are the x and y intercepts for this equation y=−1/4x+2?<br> (_,_)
Firdavs [7]

Answer:

(8, 0) is the x-intercept

(0, 2) is the y-intercept

Step-by-step explanation:

The y-intercept = 2 since the equation is in slope-intercept form.

The x-intercept occurs when y = 0

So,   0 = -1/4x + 2

        0 = -x + 8

         x = 8

(8, 0) is the x-intercept

(0, 2) is the y-intercept
