31=2y-5
Add 5 on both -5+5 which cancels out and 31+5 which is 36 and then divide 36 by 2 which equals to 18.
So y=18 hope this helped (':

Step-by-step explanation:
Answer:
y = - 3x + 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (2, 1) and (x₂, y₂ ) = (5, - 8)
m =
=
= - 3 , thus
y = - 3x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (2, 1) , then
1 = - 6 + c ⇒ c = 1 + 6 = 7
y = - 3x + 7 ← equation of line
Hey there! :D
y=2x-9
We can plug that in as y, since y is equal to 2x-9.
5x-3(2x-9)= 23
Distribute.
5x-6x+27= 23
-1x+27=23
Subtract 27 on both sides.
-1x=-4
Divide both sides by -1.
x=4
Now, plug that in for y.
y=2(4)-9
y=8-9
y=-1
(4,-1) <== solution
I hope this helps!
