Question

Please help~ ( I've been working on this problem for like a hour)
triangle PQR has vertices P (4,-1),Q(-2,7), and R (9,9) a) find an equation (in standard form) of the median from R
b) find an equation (in standard form) of the altitude from R

Answer 1

The triangle looks like this

Answer 2

as i recall, the median extends from a vertexs to the midpt of the opposite side

Answer 3

use the midpt formula to find the midpoint of PQ

Answer 4

k

Answer 5

the midpt is 10

Answer 6

wait I did something wrong....

Answer 7

then, using the coordinates of hte midpoint and the coordinates of the vertex R, find the slope of hte line tha t is the median; then use the point slope form to complet e it

Answer 8

the midpoint has two coordinates

Answer 9

take the average of the s and y coordinates to obtain (3.1) for the midpoint

Answer 10

and that is x coord not s

Answer 11

oh

Answer 12

now find the slope of the line that has the coords. (3,1) andn(9,9)

Answer 13

should look something like this: m=(9-1)/(9-3)

Answer 14

isn't it (1,3)?

Answer 15

sorry, a disleexic moment

Answer 16

you are right

Answer 17

its ok , your helping me :3

Answer 18

i wil help you finish the problem. lol. i actually am a math teacher

Answer 19

ok, so you have a slope of???

Answer 20

not yet

Answer 21

k

Answer 22

3/4?

Answer 23

i think you ereversed the formula

Answer 24

isn't it m= 9-3/9-1?

Answer 25

so the answer would be 6/8 and simplify to 3/4, right?
