Answer:
The equation for the line that passes through the points (4,8) and (6,2)
is y + 3 x -20 = 0
Step-by-step explanation:
Here, the given points are (4,8) and (6,2)
So, the slope of the equation joining two points is ![m = \frac{y_2- y_1}{x_2 - x_1} = \frac{2-8}{6-4} =\frac{-6}{2} = -3\\](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%7By_2-%20y_1%7D%7Bx_2%20-%20x_1%7D%20%20%3D%20%5Cfrac%7B2-8%7D%7B6-4%7D%20%3D%5Cfrac%7B-6%7D%7B2%7D%20%20%3D%20-3%5C%5C)
⇒Slope of the given line is m = -3
Now, by POINT SLOPE FORMULA:
Equation of a line is (y - y0) = m (x-x0)
Here, equation of the line with (x0, y0) = (6,2) is
y - 2 = (-3)(x - 6)
or, y -2 = -3x + 18
⇒ y+ 3x -20 = 0
Hence, the equation for the line that passes through the points (4,8) and (6,2) is y+ 3x -20 = 0
$39.40 all together. You would multiply the cost of 2.90 by the amount needed which is 6 and get you an answer of 17.4. Then you would multiply the cost of 4.40 by the amount needed which is 5 and get you the answer of 22. You would then add the sums 17.4 and 22 and get you your answer of $39.40
Answer:
This would depend on how big the room is. U cant evaluate without the total. Sorry!

So i can rank up ;D
y = 3 is the line of reflection
Under a reflection in a line, corresponding points of the original and it's image should be equidistant from the line of reflection
y = 3 is the horizontal line passing through all the points with a y-coordinate of 3
A is 1 unit above and A' is 1 unit below the line
B is 3 units above and B' is 3 units below
C is 1 unit below and C' is 1 unit above
D is 1 unit below and D' is 1 unit above
The vertices of the figure and the image are all equidistant from y = 3
Answer:
They sound like objectives for a unit of a math or economics class.
Step-by-step explanation:
Data collection would most likely mean analyzing collected data (looking for trends).
Constructing graphs would probably mean making graphs from a set of data (plotting the information).
Interpreting graphs would mean the opposite of the above definition: would look at a graph and then put that information into written form/
Drawing a line of best fit means making a line on a graph that represents the average of all of the data on the graph.
I hope that this helps!
