If R= {(1,2), (3,4), (5,6), (8,9)} find the domain and range of R a. Find value of X and Y.​

<h2>The Domain and Range of a Set of Ordered Pairs</h2><h3>Answer:</h3>

Domain: x \in \{ 1, 3, 5, 8 \}

Range: y \in \{ 2, 4, 6, 9 \}

<h3>Step-by-step explanation:</h3>

We are given the set of ordered pairs: R. The Domain is just the set containing all the x values of each ordered pair of R. Recall that in the ordered pair (a,b), a is the x value. In set R, we can see that the x values are \{ 1, 3, 5, 8 \}.

For the Range, it is just the set containing all the y values of each ordered pair of R. Recall that in the ordered pair (a,b), b is the y value. In set R, we can see that the y values are \{ 2, 4, 6, 9 \}.

There’s probably an easier way to do it like with the equation to find the area of a trapezoid but i did it this way bc it’s easier for me

i split the trapezoid into a triangle and a square
with the pythagorean theorem i found the missing side length to find the area of the square (length X width)
then found the area of the triangle (base X height divided by 2)

THE ANSWER IS 68.9 CM

The slope of the given line is -1/3. The perpendicular line's slope is the opposite reciprocal of the given line's slope. So, the perpendicular line's slope is 3. Then we have slope intercept form y=mx+b

y=3x+b
We don't know "b" which is the y-intercept for this equation, but we have the coordinates (6, -1). We can use these to find the slope by plugging them into the equation.

-1=3(6)+b
-1=18+b
-1-18=18+b-18
-19=b
So, the resulting y-intercept is -19.

The final perpendicular equation would be y=3x-19
