What is the point-slope form of a line with slope that contains the point (-3, 6)?
A. Y-6 = f(x+3)
B. y+6 = (x+3)
C. Y-3 = {(x+3)
D. Y- 6 =-3(x+3)

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,

3 3 6, because in every triangle the longer side is always shorter than the sum of the other two
