Answer:
y=1.5x+2.5
Step-by-step explanation:
First you find the slope:
or
lets change it into 1.5
Then write it in point-slope: (I used (1,4))
y-4=1.5(x-1)
y-4=1.5x-1.5
y=1.5x+2.5
How do you prove that a point on a perpendicular bisector is equidistant from the endpoints of the segment it intersects?
1 answer:
Check the picture drawn
Consider the line segment AB,
let M be the midpoint of AB, so AM=MA
erect the perpendicular MT to AB from point M. Pick a point P on MT and join it to the points A and B
The triangles PMA and PMB are congruent from the Side Angle Side congruence postulate:
AM=MA, PM is common and m(PMA)=m(PMB)=90°, as MT is perpendicular to AB
so PA=PB
