Which set of ordered pairs is a function?
DochEvi [55]
A function is a set of ordered pairs in which no two different ordered pairs have the same x -coordinate. An equation that produces such a set of ordered pairs defines a function. What is the catch? There can be at most one output for every input.

A equation for (7,2) and (2,12)
alexira [117]

Well to find this line you want to know the slope and the y-intercept. So find the slope:

(y2-y1)/(x2-x1)

12-2 = 10

2-7 = -5

10/-5 = 2/-1

-2 is your slope

Now for y-intercept, find the point closest to the y-axis. That is the point (2,12), and if your slope is negative 2, that means that if you go up 4 and left 2, you should find the y-intercept:

12 + 4 = 16

16 is your y-intercept

So now lets write this out in an equation:

y = mx + b

m = slope

b = y-intercept

y = -2x + 16

there you go! hope this helps!

Answer:

  (5, 1) or maybe (h, k)

Step-by-step explanation:

The given form has no letters other than the variable. The vertex in this vertex-form equation can be read from the expression as (5, 1).

In the generic vertex form ...

  f(x) = a(x -h)² +k

the letters (h, k) are used to represent the vertex.

__

You would need to consult your curriculum materials to see what letters your author uses for the vertex in vertex form.

What are the slope and the y-intercept of the linear function that is represented by the graph?
Serhud [2]

Answer:

The first option

Step-by-step explanation:

The slope m can be calculated using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, - 2) and (x₂, y₂ ) = (3, 0) ← 2 points on the line

m = \frac{0+2}{3-0} = \frac{2}{3}

The y- intercept is the point on the y- axis where the line crosses, that is - 2

Thus slope = \frac{2}{3} and the y- intercept is - 2
