For the set of ordered pairs shown, identify the domain and range. Does the relation represent a function? {(1, 8), (5, 3), (7, 6), (2, 2), (8, 4), (3, 9), (5, 7)}

It is one-many relation.

Step-by-step explanation:

Every element or x-compound is more than y- compound.

I hope you understand

Mark me as brainliest.

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4

the answer is 18 units because there are 18 small cubes inside the rectangle

hope this and p.s i am also in k12
