Determine whether the three points A(-2,-1), B(0,4) and C(2,9) all line on the same line.

sashaice [31]

All three of them do exist on the line y = 2.5x + 4

In order to find the answer to this question, start by finding the line for two points. For this example, we'll use A and C.

First we need to find the slope.
(y1 - y2)/(x1 - x2)
(9 - -1)/(2 - -2)
(9 + 1)/(2 + 2)
10/4
2.5

Now using slope intercept form and point A, we can determine the intercept of that line as well.

y = mx + b
-1 = 2.5(-2) + b
-1 = -5 + b
4 = b

So now we know A and C form the line y = 2.5x + 4. We can then check if B fits that line.

y = 2.5x + 4
4 = 2.5(0) + 4
4 = 0 + 4
4 = 4 (TRUE)

Therefore, it also falls on that line.

HI. Can you help???

Answer:

The maximum rate of change is between second 15 and second 19.

Step-by-step explanation:

See the attached table.

The table shows the total distance a spider traveled after a light was turned on.

Now, the average rate of change between two consecutive times in the table is given by

= $\frac{\textrm {Total change in Distance in feet}}{\textrm {Total change in Time in seconds }}$

Therefore, between second 5 and second 11, the average rate of change = $\frac{7 - 4}{11 - 5} = 0.5$

Between second 11 and second 15, the average rate of change = $\frac{13 - 7}{15 - 11} = 1.5$

Between second 15 and second 19, the average rate of change = $\frac{20 - 13}{19 - 15} = 1.75$

Between second 19 and second 28, the average rate of change = $\frac{24 - 20}{28 - 19} = 0.44$

Therefore, the maximum rate of change is between second 15 and second 19. (Answer)

It's #25 guys. Show your work!

Ronch [10]

$y+8 = \frac{1}{2}(x-7)$ is equivalent to <span> $y-(-8) = \frac{1}{2}(x-7)$

That is in the form </span><span> $y-y_{1} = m(x-x_{1})$ which is point slope form

In this case,

m = 1/2 is the slope
(x1,y1) = (7,-8) is the point the line goes through</span>
