Answer:

Yes the relationship is linear and given by:

y+2=-\frac{5}{4} \,(x+9) (first option of your list)

Step-by-step explanation:

Yes, it is a linear expression. As we did in previous exercises, we calculate the difference between consecutive y values of the table, and write down the answers we get:

-7-(-2) = -7+2 = -5

-12-(-7) = -12 +7 = -5

-17 - (-12) = -17 + 12 = -5

We notice that all of them give "-5"

Now we evaluate the difference between consecutive x-values in a similar fashion:

-5 -(-9) = -5+9 = 4

-1-(-5) = -1+5 = 4

3-(-1) = 3+1 = 4

We see that they all give 4 as the difference.

That means that the rate of change \frac{y_2-y_1}{x_2-x_1} =\frac{y_3-y_2}{x_3-x_2}=\frac{y_4-y_3}{x_4-x_3}=\frac{-5}{4}

This means that the slope (rate of change) of the line is "-5/4"

We can now use the general point-slope form to write the equation of the line, using the first pair of the table as our selected point, and using "-5/4" for the slope:

y-y_0=m\,(x-x_0)\\y-(-2)=-\frac{5}{4} \,(x-(-9))\\y+2=-\frac{5}{4} \,(x+9)

which is the first expression listed among your possible answer choices.

Zolol [24]

Step-by-step explanation: What you do first is find the volume of the room which is 1,610. So after that you multiply 1,610 by 2 since Maria wants "two" coats of paint on each wall.

PLEASE HELP ME! A skydiver parachutes to the ground. The height y (in feet) of the skydiver after x seconds is y = -10x + 3000.
tatuchka [14]
A) Plot a point at (0, 3000), then subtract 10 for every second that passes by.
B) The slope is negative because the skydiver is falling and the graph is plotting his descent, his x intercept is at (300, 0) which means he will touch land after 300 seconds
To find the the x intercept, make y equal 0 so 0=-10x+3000, subtract by 3000 on each side, and you end up with -3000=-10x, you then divide both sides by -10 and you end up 300=x or x=300
