Answer:

Step-by-step explanation:

The point-slope form of an equation of a line:

$y-y_1=m(x-x_1)$

m - slope

(x₁, y₁) - point on a line

We have the slope m = -5, and the point (-1, -3). Substitute:

$y-(-3)=-5(x-(-1))\\\\y+3=-5(x+1)$

Convert to the slope-intercept form (y = mx + b):

$y+3=-5(x+1)$ <em>use the distributive property</em>

$y+3=-5x-5$ <em>subtract 3 from both sides</em>

$y=-5x-8$

Item 12 You win an online auction for a toy. Your winning bid of $52 is 65% of your maximum bid. How much more were you willing

Answer:

$28

Step-by-step explanation:

Given that:

Value of Winning bid = $52

Winning bid 65% of the maximum bid.

To find:

How much more is the maximum bid from the winning bid ?

Solution:

We are given that the winning bid is 65% of the maximum bid.

Using this percentage value, we need to first find the value of maximum bid and then we need to subtract the value of winning bid from the maximum bid to find the answer.

Let the value of maximum bid = $ $x$

As per question statement:

$65%\ of\ x = 52\\\Rightarrow \dfrac{65}{100} \times x =52\\\Rightarrow 5x = 400\\\Rightarrow x = \dfrac{400}{5}\\\Rightarrow x =\$80$

Therefore, maximum bid = $80

Our answer is:

$80 - $52 = <em>$28</em>

Answer:

the possible line of best fit equation is;

y = 10x + 24

Step-by-step explanation:

Here, we want to get the approximate line of best fit

Mathematically, we have the general line of best fit as

y = mx + b

where m is the slope and b is the y-intercept

By joining the given lines, we can see that the y-intercept values fall a little below 30

This means that the possible y-intercept value is 24

Now, to get the slope value, we select any two points and use the slope equation

We can have (3,50) and (6,80)

Using the slope equation;

m = (y2-y1)/(x2-x1) = (80-50)/(6-3) = 30/3 = 10

The equation is thus;

y = 10x + 24
