Question

Indicate in standard form the equation of the line passing through the given points.

R(3, 3), S(-6, -6)

Answer 1

first find slope of the line with this formula
\[m=\frac{ y _{R} - y _{S} }{ x_{R}-x _{S} }\]

Answer 2

@amirreza1870 I got 0...

Answer 3

no.\[\frac{ -6-3 }{ -6-3 }=\frac{ -9 }{ -9 }=1\]

Answer 4

oh ok and then what do I do?

Answer 5

then use one of points for example R .and use this formula .
\[y-y _{R}=m(x -x_{R})\]

Answer 6

I got 3+6 = 1(3+6)
is that correct?
then I got 9= 1(9)

Answer 7

no. only use R point
y-3=1(x-3)
y-3=x-3
y=x

Answer 8

@amirreza1870 I'm not a genius in geometry :( can you help me

Answer 9

@amirreza1870 is it x-y= 0?

Answer 10

yes
x-y=0 so x=y

Answer 11

Omg! Thank you sooo muchhh
