Please actually answer this it has a good amount of points!
Vanyuwa [196]

The answer is D, "No, because two points with the same x-value have different y-values."

Essentially, there cannot be more than one point on the same x-line. Point (2, 11) and point (2, 2) are on the same x-line, which is 2.

Hope this helps!

Use the model from problem 12 to estimate the population of bacteria at 9 hours. Type your answer below. Show your work.
astra-53 [7]
Check the picture below.

that's done just with the provided links, and I simply ran a line, so it'll be thereabouts, roughly between 13 and 14, depending on how you hang the line.

anyhow, if you have a TI(texas instruments) 89+ or higher, you can just provide the value pairs of the data and run a quadratic regression, or an exponential.

there are some online regression calculators as well.

Stuck Please help...... 1,2,5,6
marusya05 [52]

Slope-intercept form:

y = mx + b    "m" is the slope, "b" is the y-intercept


For lines to be parallel, they have to have the SAME slope.


1.) The given line's slope is -7/5, so the parallel line's slope is also -7/5

y=-\frac{7}{5}x+b    Plug in (2, -3) to find "b"

-3 = -\frac{7}{5}(2)+b

-3=-\frac{14}{5}+b       Add 14/5 on both sides

-3+\frac{14}{5}=b     Make the denominators the same

\frac{-15}{5}+\frac{14}{5} =b\\-\frac{1}{5}=b


y=-\frac{7}{5}x-\frac{1}{5}



2.) The given line's slope is 1/2, so the parallel line's slope is also 1/2

y = 1/2x + b     Plug in (4,5) to find "b"

5 = \frac{1}{2}(4) + b

5 = 2 + b

3 = b


y=\frac{1}{2} x+3


5.) The given line's slope is -2/5, so the parallel line's slope is also -2/5

y = -2/5x + b      Plug in (-5, -4)

-4 = -2/5(-5) + b

-4 = 2 + b

-6 = b


y=-\frac{2}{5}x-6



6.) -5x + 2y = 6    Isolate "y", add 5x on both sides

2y = 6 + 5x       Divide 2 on both sides

y = 3 + 5/2x

The slope is 5/2, so the parallel line's slope is also 5/2

y = 5/2x + b      Plug in (-3,2)

2 = 5/2(-3) + b

2 = -15/2 + b   Add 15/2 on both sides

2 + 15/2 = b      Make the denominator the same

4/2 + 15/2 = b

19/2 = b


y=\frac{5}{2}x+\frac{19}{2}
