Hey there! I'm happy to help!
First, let's find the slope. To find it, you divide the difference in two y values by the difference in the corresponding x values.
The x values are what you can choose. You can choose the number of minutes you choose, but you cannot directly choose the cost. You control the minutes, which dictates what the cost is. So, the minutes are our x values and the costs are our y values.
Let's use the points (500,62) and (750,77).
We subtract the y values.
77-62=15
We subtract the x values.
750-500=250
We divide these.
15/250=0.06
This means that our slope is 0.06, which means that for every minute the cost goes up by six cents.
The slope intercept equation is y=mx+b. The m is slope and b is y-intercept. We already have the slope, but we need the y-intercept. We can plug in the slope and one point on the line to solve for b.
62=0.06(500)+b
Flip the equation so b is on the left.
0.06(500)+b=62
30+b=62
Subtract 30 from both sides.
b=32
Therefore, our equation is y=0.06x+32.
Have a wonderful day! :D

<u><em>The complete question is</em></u>
Bianca is trying to find the area of this rectangle. She already measured one side as 10 cm. Which other length(s) could she measure to use in her area calculation?
The picture of the question in the attached figure
we know that
The area of rectangle is equal to
![A=LW](https://tex.z-dn.net/?f=A%3DLW)
where
L is the length of rectangle
W is the width of rectangle
Remember that
The opposite sides of a rectangle are parallel and congruent and the measure of each interior angle is 90 degrees
That means---> The length and the width are perpendicular
In this problem we have
![L=10\ cm](https://tex.z-dn.net/?f=L%3D10%5C%20cm)
we have that
The width is equal to
![W=b=c](https://tex.z-dn.net/?f=W%3Db%3Dc)
so
The area of rectangle is equal to
or ![A=10c\ cm^2](https://tex.z-dn.net/?f=A%3D10c%5C%20cm%5E2)
therefore
To find out the width, Bianca could measure segments b or c, because they form a 90 degrees angle with the length
No, it is not, a parabola, (from this equation, which is x^2, disregarding the +8 or y-intercept) cannot be a one-to-one function, it is a many-to-one.
