Determine whether the table of values below represents a linear function. If it represents a linear function, write the function

Rzqust [24]

Answer:

The equation of a linear function is:

$y = 2x+4$

Step-by-step explanation:

Given the table

x y

-10 -16

-3 -2

1 6

2 8

Determining the slope between the points (-10, -16), (-3, -2)

$\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}$

$\left(x_1,\:y_1\right)=\left(-10,\:-16\right),\:\left(x_2,\:y_2\right)=\left(-3,\:-2\right)$

$m=\frac{-2-\left(-16\right)}{-3-\left(-10\right)}$

$m=2$

Determining the slope between the points (-3, -2), (1, 6)

$m=\frac{6-\left(-2\right)}{1-\left(-3\right)}$

$m=2$

Determining the slope between the points (1, 6),(2, 8)

$m=\frac{8-6}{2-1}$

$m = 2$

As the slope between the points is the same. Thus, the table represents the linear function.

Using the point-slope form of the line equation

$y-y_1=m\left(x-x_1\right)$

substituting the values m = 2 and any point let say (1, 6)

$y - 6 = 2(x-1)$

$y-6 = 2x-2$

$y = 2x-2+6$

$y = 2x+4$

Therefore, the equation of a linear function is:

$y = 2x+4$

Write the equation of the line passing through (−1, 0) and (0, −3).

iragen [17]

Answer:

y = -3x -3

Step-by-step explanation:

We have two points so we can find the slope

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

m = (-3-0)/(0--1)

= (-3-0)/(0+1)

= -3/1

= -3

We have the slope and the y intercept (where x=0) The y intercept is -3

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

y = -3x -3

Pita has 12 coins in her bag.

Allushta [10]

Answer:27/220

Step-by-step explanation:

She must have 2 �1 coins and 1 50p coin.

She can choose the 2 �1 coins 3C2 = 3 ways.

For each of those 3 ways she can choose the

50p coin 9C1 or 9 ways.

That's 3�9=27 ways to get �2.50.

She can choose any 3 coins in 12C3 = 220 ways.

The desired probability is 27 ways out of

220 ways,or 27/220, or 13.5% of the time.
