Question:

What is the equation of the following line? Be sure to scroll down first to see all answer options. ( 0, 0) (2, -8)

Answer:

The equation of line is y = -4x

Solution:

Given points are ( 0, 0) (2, -8)

Find the slope of line

$m = \frac{y_2-y_1}{x_2-x_1}$

From given,

$(x_1, y_1) = (0, 0)\\\\(x_2, y_2) = (2, -8)$

Substituting the values we get,

$m = \frac{-8-0}{2-0}\\\\m = -4$

The equation of line in slope intercept form is given as:

y = mx + c --------- eqn 1

Where,

m is the slope of line

c is the y intercept

Substitute m = -4 and (x, y) = (0, 0) in eqn 1

0 = -4(0) + c

c = 0

Substitute m = -4 and c = 0 in eqn 1

y = -4x + 0

y = -4x

Thus the equation of line is y = -4x

1.If a number is chosen at random from the integers 5 to 25 inclusive , find the probability that the number is a multiple of 5

Drupady [299]

I'll do problem 1 to get you started.

set A = multiples of 3 between 5 and 25 = {6, 9, 12, 15, 18, 21, 24}

there are 7 items in set A, so we can say n(A) = 7

set B = multiples of 5 between 5 and 25 = {5,10,15,20,25}

Here we have n(B) = 5

set C = multiples of 3 and 5, between 5 and 25 = {15}

n(C) = 1 which we can rewrite as n(A and B) = 1.

-----------------------------------------

To summarize so far,

n(A) = 7
n(B) = 5
n(A and B) = 1

From those three facts, then we can say,

n(A or B) = n(A) + n(B) - n(A and B)

n(A or B) = 7 + 5 - 1

n(A or B) = 11

There are 11 values between 5 and 25 that are multiples of 5, multiples of 3, or both.

Those 11 values are: {5, 6, 9, 10, 12, 15, 18, 20, 21, 24, 25}

This is out of 25-5+1 = 21 values overall which are in the set {5,6,7,...,24,25}

So we have 11 values we want out of 21 overall, which leads to the probability 11/21

Final Answer: 11/21
