Point slope form:
Y= m(x-x1) + y1
M= slope
(X1, y1) point that line passes through
Answer: y= 4(x+ 8)
There’s technically two answers, you could put Angles 3 and 6, or Angles 7 and 2
X^2 - 80 = 0
x^2 = 80 ...take the square root of both sides, eliminating the ^2
x = (+-) sqrt 80
x = (+-) sqrt 16 * 5
x = (+-) 4 sqrt 5
so x = 4 sqrt 5 or x = -4 sqrt 5
Explanation:
NO, because, collinear means 'points on the same line'
all 3 points of a triangle are not on the same line. They are 3 different points. Therefore, they are not collinear.
