pls help me this is worth half of my grade

Answer: y = 5184x

Step-by-step explanation:

Yes, there is a relationship because, logically, there should be a set amount of pixels changing when the area changes. This data table shows a linear relationship between the square inches of the screen and the number of pixels. To create a linear equation, we need to know the parent function for linear equations: y=mx + b, where "m = rate of change" and "b = initial value or y-intercept"

To find the rate of change (i.e., the slope). To find the rate of change of a linear function, use the formula (y2-y1)/(x2-x1). This formula works because it's essentially using the "rise/run" method of finding the rate of change.

Using the rate of change formula:

(373248-31104) / (72-6) = 5184

We know the rate of change is 5184, and now we simply have to find the "b" value, which is the y-intercept. We do this by plugging in values we know into the y=mx + b equation.

m = 5184, and we can use any set of points in the table for "x" and "y"

31104 = 5184(6) + b

Now, we isolate "b":

31104 - 5184(6) = b

0 = b

The y-intercept ("b" value) is zero, so we can now plug that into our equation:

y = 5184x + 0

y = 5184x

Chad washes windows after school to make some extra money. He charges $5.50 to wash each window. If the customer provides the supplies, Chad deducts $3.25 from the total cost. One customer paid a total of $27.50 and did not provide supplies. Which equation could be used to find the number of windows, w, that Chad washed for this customer?

A 5.5 - 3.25 w = 27.5
B 5.5 w - 3.25 = 27.5
C 5.5 w + 3.25 = 27.5
D 5.5 w = 27.5

A wheat farmer plows 5 acres of land and collects 135 bushels of wheat. The next day, the farmer plows 8 acres of land and collects 216 bushels of wheat.

Is there a proportional relationship between the number of bushels of wheat collected and the number of acres plowed over the two days? Explain.

Yes, it is proportional because the farmer collected 7 bushels for every 1 acre plowed.
Yes, it is proportional because the farmer collected 27 bushels for every 1 acre plowed.
No, it is not proportional because both variables cannot be zero at the same time.
No, it is not proportional because all ratios between the number of bushels collected and the number of acres plowed are not equivalent.
