Answer:
y = 5x-11
Step-by-step explanation:
The slope intercept form of a line is y =mx+b where m is the slope
y = -1/5 x-3
The slope is -1/5
Lines that are perpendicular have negative reciprocal slopes
-1 /(-1/5)
-1 * -5/1
5
The slope of the line that is perpendicular is 5
y=5x+b
Using the point (4,9)
9 = 5(4)+b
9 = 20+b
9-20 =b
-11
y = 5x-11
(24,18)(28,21)
slope(rate of change) = (21 - 18) / (28 - 24) = 3/4 <==
Answer:

Step-by-step explanation:
So we have the equation:

First, let's distribute the left side of our equation:

Multiply:

Now, let's isolate the y-variable. Subtract 4y from both sides:

The right side cancels. Subtract on the left. So:

Now, subtract 5 from both sides:

The left side cancels. Subtract on the right:

Now, divide both sides by 6. So:

The left will cancel. Therefore:

And we're done!
The answer to the equation can be easily solved with division. You take the total amount and divide it by the number of sold units
$234 / 18 = y
