Perpendicular to y=2x+3 through (2, -3)
Reika [66]

Hello!

To find the line perpendicular to the given line, y = 2x + 3, firstly, find the slope of the perpendicular line. To find it, use this format: -1/m, where m is the slope. It is also called the "negative reciprocal" of the slope of the given line.

Then, you substitute an ordered pair into a new slope-intercept equation (with the slope) and find the y-intercept.

-1/m when m = 2 → -1/2

y = -1/2x + b (substitute the given ordered pair)

-3 = -1/2(2) + b (simplify)

-3 = -1 + b (add 1 to both sides)

-2 = b | The y-intercept of the perpendicular equation is -2.

Therefore, the line perpendicular to the given equation, that also goes through the given ordered pair is y = -1/2x - 2.

Each graph shows a relation. The first and second numbers of each ordered pair in the relation are members of the set of real nu
Goshia [24]

Using it's concepts, we have that:

  • The domain of the relation is of -2 ≤ x ≤ -1.
  • The range of the relation is of -2 ≤ y ≤ 2.
  • Since each value of the input is mapped to only one value of y, it is a function.

<h3>What are the domain and the range of a relation?</h3>

  • The domain of a relation is the set that contains all possible input values for the relation. In a graph, it is given by the values of x.
  • The range of a relation is the set that contains all possible output values for the relation. In a graph, it is given by the values of y.

Hence:

  • The domain of the relation is of -2 ≤ x ≤ -1.
  • The range of the relation is of -2 ≤ y ≤ 2.

<h3>When does a relation represents a function?</h3>

A relation represents a function when each value of the input is mapped to only one value of the output.

From this graph, we have that <u>each value of x is mapped to only one value of y</u>, that is, there are no vertically aligned points, hence the relation is a function.
