<span>Find the slope of the line going through the points (-9, -6) and (-18, -6).
+ The equation is y = ax+b
+ we have -6= -9a+b or b= 9a- 6
and the second: -6= -18a+b or -6= -18a+ 9a-6 or -9a=0 and a=0, b= 9*0-6= -6
The equation is: y= -6
and the slope is a=0

Using elimination you can eliminate 'y' to find x first.
4x=24
+ 5x=12
-------------
9x=36
9/9 x=36/9
X=4
Next use substitution to plug 4 back in to 'x'
4(4)+y=24
16+y=24
-16 -16
------------
Y=8
X is 4 and Y is 8
Nothing shows up.. could you type it out?
Answer:
Hi there!
The answer to this question would be:
Step-by-step explanation:
the general equation would be: y= -1/2x + 17/2
first you want to solve for the slope (m): you wanna do delta y (change of y ) over delta x (change of x)
so it goes like (11-9)/(-5-(-1)) and you get -1/2
then you want to solve for the y intercept (b)
so you plug in one of the point that you were given, in this case I am using (-1,9)
so now the equation looks like 9 = 1/2 +b then solve for b and you get b=17/2
