-2x=4x+9 |-4x
-6x=9 |:(-6)
x=-1,5
Check:
-2*-1,5=4*-1,5+9
3=-6+9
3=3
Answer:
y=1/3x-8
Step-by-step explanation:
The slope intercept form of a line is y=mx+b
m stands for slope and b stands for y intercept
So ... simply put 1/3 in for m and -8 in for b
Answer:
4
Step-by-step explanation:
5 + 3/1 + 1 =
8/2 =
4/1 =
4
This is because of slope formula which is x-x/y-y
You're almost looking at the solution. Almost.
If it only said " r = 1 ", then that would be the solution right there.
But it says " | r | = 1 ", so there's a little more to it.
'r' can be either +1 or -1 and that equation will be a true statement.
So +1 and -1 are both solutions.
