If I was
to
asked
think of
a number and multiply it by
3, ! could write this algebrically
as 2x
Write the following
Algebrically

using X as your unknown

I think of a number
take away 1 and muti-
ply result by 3

Let the number be x

Step 1

Step 2

Hence, The final equation is x-1×3

found it xd it ok yt

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.
