16 question Write a rule for the linear function in the table

Mathematics
1 answer:
Ira Lisetskai [31]4 years ago
4 0
To write the rule or equation of the linear function we need to find the slope of the function first. Using any two points we can find the slope.

Using the first two points (-3, -1) and (0, 2).

Slope (m) of the function would be:

m= \frac{-1-2}{-3-0}= \frac{-3}{-3} =1

Using slope and the point (0,2) we can write the equation of the line as:

y - 2 = 1(x-0)
y = x + 2

Thus, the correct rule for the given linear function is x+2

Which graph shows a set of ordered pairs that represent a function?<br><br>Need help​
Sveta_85 [38]

Answer:

The third graph, the top right graph

Step-by-step explanation:

A function when determined graphically is a graph that passes the straight line test, which means if there is any two points on the graph which you can plot a vertical straight line going through both of them it is not a function.  If 1 x value is equal to 2 y values, it is not a function.

For each situation below, write the equation of the line and explain how you can tell.
sveticcg [70]

Answer:

see below

Step-by-step explanation:

a. Has a slope of 2 and passes through (10,17)

Using the slope intercept form

y = mx+b  where m is the slope and b is the y intercept

y = 2x+b

Substitute the point into the equation

17 = 2(10)+b

17 = 20+b

Subtract 20 from each side

17-20 =b

-3 =b

y = 2x-3

b. passes through (1,-4) and (2,-5)

First find the slope

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

   = (-5- -4)/(2-1)

  = (-5+4)/(2-1)

  = -1/1

  = -1

Using the slope intercept form

y = -x+b

Substitute a point into the equation

-4 = -1(1) +b

-4 = -1+b

Add 1 to each side

-3 = b

y = -x+3

The possible values of x are given by x+8=&lt;6.<br><br>The greatest possible value of 7x is_____​
kozerog [31]

Answer:

The possible values of x is given by x\leq  -2 and they include: -2, -3, -4, -5, -6 and so on

The greatest possible value of 7x is -14

Step-by-step explanation:

We are given the equation: x + 8 <= 6

Let collect the like terms:

x + 8 \leq  6\\x\leq  6 -8\\x \leq  -2

Therefore, x <= -2 and the possible values include: -2, -3, -4, -5, -6 and so on

To find the greatest possible value of 7x is when x = -2.

7x = 7 * -2\\7x = -14\\.
