Hope this helps plz hit the crown :D
Slope = (y2 - y1) / (x2 - x1)
(-1,3)....x1 = -1 and y1 = 3
(1,-1) ...x2 = 1 and y2 = -1
now we sub
slope = (-1 - 3) / (1 - (-1) = -4/2 = -1/2 <==
Answer:
3!
Step-by-step explanation:
You add 1 with two to get 3!
<u>Answer-</u>
<em>The coordinates of the orthocenter of △JKL is (-4, 8)</em>
<u>Solution-</u>
The orthocenter is the point where all three altitudes of the triangle intersect. An altitude is a line which passes through a vertex of the triangle and is perpendicular to the opposite side.
For a right angle triangle, the vertex at the right angle is the orthocentre of the triangle.
Here we are given the three vertices of the triangle are J(-4,-1), K(-4,8) and L(2,8)
If the triangle JKL satisfies Pythagoras Theorem, then triangle JKL will be a right angle triangle.
Applying distance formula we get,
![JK^2= (-4+4)^2+ (8+1)^2=0+81=81\\\\KL^2= (-4-2)^2+ (8-8)^2=36+0=36\\\\JL^2= (-4-2)^2+(8+1)^2=36+81=117](https://tex.z-dn.net/?f=JK%5E2%3D%20%28-4%2B4%29%5E2%2B%20%288%2B1%29%5E2%3D0%2B81%3D81%5C%5C%5C%5CKL%5E2%3D%20%28-4-2%29%5E2%2B%20%288-8%29%5E2%3D36%2B0%3D36%5C%5C%5C%5CJL%5E2%3D%20%28-4-2%29%5E2%2B%288%2B1%29%5E2%3D36%2B81%3D117)
As,
![\Rightarrow 117=81+36](https://tex.z-dn.net/?f=%5CRightarrow%20117%3D81%2B36)
![\Rightarrow JL^2=JK^2+KL^2](https://tex.z-dn.net/?f=%5CRightarrow%20JL%5E2%3DJK%5E2%2BKL%5E2)
![\Rightarrow \text{JKL is a right angle triangle}](https://tex.z-dn.net/?f=%5CRightarrow%20%5Ctext%7BJKL%20is%20a%20right%20angle%20triangle%7D)
![\Rightarrow \angle K=90^{\circ}](https://tex.z-dn.net/?f=%5CRightarrow%20%5Cangle%20K%3D90%5E%7B%5Ccirc%7D)
Therefore, the vertex at K (-4, 8) is the orthocentre.
