A picture is enlarged by keeping its width the same and increasing its length. The scatter plot shows the perimeter of the pictu
natima [27]
Since you have not included the plot, I'll just tell you how to find the function of the graph that you are looking for.
Function of the straight line has the general formula: y = mx + c
where: 
m is the slope of the line and c is the y-intercept

So first we will need to find the slope (m):
Taking two points from the graph (x1,y1) and (x2,y2), the slope can be calculated as follows:
m = (y2-y2) / (x2-x2)

Then, we will need to find the y intercept.
we have the equation y = mx + c and we have m calculated
Take any point that belongs to the line and substitute with the values of x,y and m and then calculate c.

Now you have both m and c calculated, just substitute with the values in the formula.

Knowing that a is inversely proportional to b2 and when b=4 a is equal to 5, find the value of a when b=4/5
Flauer [41]

Answer:

a = 16

Step-by-step explanation:

inversely proportional

y = k/x

a = k/b

5 = k/4

solve for k

multiply by 4 on each side

20 =k

a = 20b

if b = 4/5

a = 20 * 4/5

a = 16

Post-test about graphs need help
Murrr4er [49]

Answer:

O A.     y=\frac{4}{3} x-\frac{1}{3}

Step-by-step explanation:

To find the equation of the line, we need to know the slope and the y-intercept.

so, let's start by the slope. We need two points given in the graph.

(4, 5) and (-2, -3)

Then use the Slope-Formula to identify the Slope of the line.

m = slope

m = \frac{y2-y1}{x2-x1}          Slope Formula

m = \frac{-3-5}{-2-4}           subtract the second y from the first y / second x from first x

m = \frac{-8}{-6}               Turn the fraction to positive because two negatives = positi-

m = \frac{8}{6}                 Simplify

m = \frac{4}{3}                 Final Answer

The slope of the line is \frac{4}{3} now what about the y-intercept?

The y-intercept is located at the y axis.

It determines how many units the graph goes up or down depending...

Well in this case, the y-intercept is negative because it is below on the yaxis

Then we must determine the y-intercept.

so we know is negative but it isn't exactly on a point so it is formed as a fra-

then we can determine it by seeing when it hits another unit (hard explainin)

y-intercept = -1/3

Final Answer: y = \frac{4}{3} x-\frac{1}{3}
