What is the domain and the range for the (2,3),(4,1),(5,-3),(-9,9)

Domain : {-9, 2,4,5}

Range:  { -3,1,3,9}

Step-by-step explanation:

The domain is the input values

The domain is the x values in the pairs

Domain : {2,4,5,-9}

We usually put them in numerical order

Domain : {-9, 2,4,5}

The range is the output values

The  range is the y values in the pairs

Range : { 3,1,-3,9}

We usually put them in numerical order

Range:  { -3,1,3,9}

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3

i can't solve unless i know what the line is
