Find the slope first
slope=(2-1)/(-1+3)=1/4=.25

now use the slope and either point to write in point slope form
y-1=.25(x-2)
y-1=¼x-½

to rationalize all the denominators multiply by the last common multiple, here we get 4
4y-4=x-2

then put in the correct order

x-4y=-2

Help!!!!!!!!!!!! &gt;&gt;&gt;&gt;&gt;Which number set contains all rational<br> numbers?
stellarik [79]

The only set that only has rational numbers is the first one:

{1/3, -3.45, √9}

<h3>Which of the given sets contains only rational numbers?</h3>

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

If we look at the first set, the elements are:

  • 1/3 which is a rational number.
  • -3.45 = -345/100 which is a rational number
  • √9 = 3 = 3/1 which is a rational number.

In the other sets we can see elements like:

√37, √44, or √2 which are all irrational numbers, then the only correct option is the first one.
