Do you remember how to find the equation of a line when you know two points on the line ? Well, that little table gives you FIVE points on the line, and in case some students didn't notice that, the table even labels the columns 'x' and 'y' as a hint. With 5 points given, there are 20 different ways to find the equation of the line. Get to work.

Okay first we need to find the line of best fit. We would need the slope and the y-intercept. First let's solve for slope.

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

We would need two coordinates from the table to fill in the data. Let's use (0, 23) and (1, 20).

(x_1, y_1) = (0, 23); (x_2, y_2) = (1, 20)

Then we can solve for the y-intercept using the slope-intercept form: y = mx + b.

What is the common ratio of the geometric sequence; *
Tanya [424]

Answer:

C

Step-by-step explanation:

The common ratio r of a geometric sequence is

r = \frac{a_{2} }{a_{1} } = \frac{\frac{10}{3} }{10} = \frac{10}{3} × \frac{1}{10} = \frac{1}{3} → C

Can I get help with this?
blagie [28]

Answer:

y-4=7(x-1)

Step-by-step explanation:

Hi there!

We are given the slope of the line (7) and the point (1,4) and we need to find the equation in point-slope form.

Point-slope form is given as y-y_{1}=m(x-x_{1}) where m is the slope and (x_{1},y_{1}) is a point

We have all of the needed information for the equation, but let's first label the values of everything in order to avoid confusion

m=7

x_{1}=1

y_{1}=4

now substitute into the formula:

<u>y-4=7(x-1)</u>

Hope this helps! :)

Because of hiring a plumber, y, to work x hours on a repair project can be modeled using a linear function. the plumber charges
seraphim [82]

Answer:

The plumbers cost would be equal to the equation 80+45x=y with y being the total amount of money he made and x being how many hours he worked.

Step-by-step explanation:

In this equation to find the amount the plumber was paid all you need to do is plug in the amount of hours he worked for x.

If the plumber worked his maximum of 8 hours then the equation would change from 80+45x=y to 80+(45×8)=440.

So, if the plumber worked for 8 hours he would make $440.
