Answer:
y = -3x + 8
Step-by-step explanation:
First, find the slope of the equation.
delta y/ delta x = (-4-11)/(4-(-1)) --> -15/5
The slope is -3
y = -3x + b
To find b, input the values of one of the ordered pairs
Using (4,-4) :
-4 = -3(4) + b
-4 = -12 + b
8 = b
The final equation is y = -3x + 8
Answer:
20
Step-by-step explanation:
The pythagorean theorem states that
So
You would then do
Because a square root is the opposite of a square.
because 20 * 20 = 400
That's exactly what he's measuring. So we can't tell,
because you haven't told us any of his measurements.
The rate of change during any 5-minute period would be
(the difference between two of his measurements)
divided by
(5 minutes)
probably in units of [cubic yards per minute].

Given:
Find:
Solution: We need to figure out the equation in slope-intercept form and the first step is to understand the slope. We know that it is going to be perpendicular to 3/2 and in order to find the perpendicular slope we must first negate it. We would then take the reciprocal of that number and in this case the slope would be -2/3. After that we just plug into the point-slope formula, simplify, distribute, and solve for y.
<u>Plug in the values</u>
<u>Simplify and distribute</u>
<u>Add 2 to both sides</u>
Therefore, after completing the steps we were able to determine that the equation the best fits the description that was provided is y = -2/3x + 4/3.
