The equations are written in point-slope form. which equation represents a line through points (-8, 3) and (2, -3)?

a. y - 3= 3(x+8)
b. y - 3= -3(x+8)
c. y - 3= -1(x+8)
d. y - 3= 1(x+8)

my dear correct answer is option number 3

isocolese triangle

we know that the line connect a and b is the hyptonuse

so first find the hypotonuse length using the distance formula, call the length c

since it is an isocolese triangle, the lengths of the legs are the same

using pythagorean theorem,

in this case, a=b since isocolese triangle so we get

or

we can find c so we can find the distances

we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c

if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where

and

intersect to find where they intersect

i'm not going to put an example because i have to go to class. i hope this explanation is enough

well, because the $0.25 is an added cost depending on how many minutes, the answer would be y = 30 + 0.25x.
