Two quantities,
x
and
y
, are directly proportional. if
x
is doubled, what happens to
y
?

Since x and y are directly proportional , it means any increment in x leads to increment in y and vice versa, so if x is doubled y is also doubled

Step-by-step explanation:

it’s supposed to be -4+45=41

step-by-step explanation:

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.
