Question

What type of triangle is RST? And calculate the equation of the line between the points (-6,-1) and (2,-1) (figure in comments)

Answer 1

@dpaInc

Answer 2

triangle RST has two equal sides... what do you call that?

Answer 3

isoscles

Answer 4

ok.... does the second question have anything to do with this triangle?

Answer 5

Yes.

Answer 6

let me get this straight.... in the second question, you want the equation of the line that goes through both (-6,-1) and (2,-1) ????

Answer 7

what does this have to do with the triangle?

Answer 8

You use the graph thats given, not the triangle

Answer 9

Sorry.

Answer 10

graph of what? the line through (-6, -1) and (2, -1) ?

Answer 11

that's just a horizontal line....

Answer 12

The question just asks :
calculate the equation of the line between the points (-6,-1) and (2,-1)

Answer 13

dont use the figure I posted

Answer 14

I got y= -1

Answer 15

yes.... y=-1 is correct.

Answer 16

good work.... :)

Answer 17

write the equation of segment AD

Answer 18

thank you. I attachted the figure

Answer 19

find the slope of AD....
do you know how?

slope = \(\huge \frac{subtract y's}{subtract x's} \)

Answer 20

-1/4

Answer 21

Right?

Answer 22

@ParthKohli

Answer 23

I need the equation of the line

Answer 24

Which one? I see two of them!

Answer 25

Oh... AD

Answer 26

It's actually -4/1

Answer 27

write an equation for segment AD

Answer 28

Yeah, right. The slope is -4/1

Answer 29

I know

Answer 30

I need to write the equation for it

Answer 31

@yummydum I need and equation for segement AD, the figure in attached

Answer 32

what do you mean by equation? ...point-slope form?

Answer 33

what level of math is this btw?

Answer 34

i think you want the "y=mx+b" ....am i right?

Answer 35

like 4x +y=7 kinda of equation

Answer 36

I need to go but please help!

Answer 37

oh standard form?

Answer 38

okay so you do \[y-y_1=m(x-x_1)\]\[y-3=-4(x-1)\]\[y-3=-4x+4\]\[4x+y-3=4\]\[4x+y=7\]
so the equation of AD is 4x+y=7 ......lol

Answer 39

@oholmes hope that helps! :)

Answer 40

sorry... got cut off last time with a power break...
slope: \(\large m_{AD}=\frac{(3)-(-1)}{(1)-(2)}= \) ???

Answer 41

-4/1

Answer 42

yes.... slope = -4

Answer 43

So if were to write the equation for segment AD it would be 4x+y=7

Answer 44

the previous post already gave you the equation in standard form you can solve for y to get it in slope-intercept form if you want. the question does not specify what form they want the equation in....

Answer 45

yes....(to your above post)

Answer 46

okay
