The points M, (−2,4), N(1,2), O(4,4), and (2,8) form quadrilateral MNOP. Find the desired slopes and lengths, then fill in the words that BEST identifies the type of quadrilateral.
To find the slopes of the sides of the quadrilateral MNOP, we can use the formula for slope which is given by:
slope = (change in y)/(change in x)
1. Slope of side MN:
slope of MN = (2-4)/(1-(-2)) = -2/3
2. Slope of side NO:
slope of NO = (4-2)/(4-1) = 2/3
3. Slope of side OP:
slope of OP = (8-4)/(2-4) = 4/-2 = -2
4. Slope of side PM:
slope of PM = (4-8)/(-2-4) = -4/(-6) = 2/3
Now, let's find the lengths of the sides:
1. Length of side MN:
Using distance formula:
length of MN = √[(1-(-2))^2 + (2-4)^2] = √[3^2 + (-2)^2] = √[9 + 4] = √13
2. Length of side NO:
Using distance formula:
length of NO = √[(4-1)^2 + (4-2)^2] = √[3^2 + 2^2] = √[9 + 4] = √13
3. Length of side OP:
Using distance formula:
length of OP = √[(2-4)^2 + (8-4)^2] = √[(-2)^2 + 4^2] = √[4 + 16] = √20 = 2√5
4. Length of side PM:
Using distance formula:
length of PM = √[(-2-(-2))^2 + (8-4)^2] = √[0^2 + 4^2] = √[0 + 16] = √16 = 4
Now, let's identify the type of quadrilateral based on the slopes and lengths.
From the slopes:
- The opposite sides MN and OP both have slopes of 2/3, which means they are parallel.
- The opposite sides NO and PM have slopes of -2 and 2/3, respectively, which means they are not parallel.
From the lengths:
- The lengths of all the sides are different.
Based on these properties, the quadrilateral MNOP can be identified as a trapezoid.
make sure to put all your answers in radical form
I apologize for that oversight. Here is the corrected response with all the answers in radical form:

Thank you
You're welcome! If you have any more questions, feel free to ask.
Are you sure the slope of pm is 2/3
Apologies for the mistake in my previous response. Let's calculate the correct slope of PM:
Slope of PM = (4-8)/(-2-(-2)) = -4/(-4) = 1
So the slope of PM is 1. Thank you for catching that error.
