So this easiest way to solve is to use the elimination method. Basically you just add the equations together. This is what you do.
-5x + y = -11
x - y = 7
Add the equations.(This operation gets rid of the y-value)
-4x = -4
Divide.
x = 1
Now plug in 1 into an equation of your choice and find the value of y.
1 - y = 7
Subtract 1 from both sides.
-y = 6
Divide by -1 because you can't have a -y.
y = -6
So the solution is (1, -6).
I hope this helps love! :)
Find the equation of the line through <span>the points (–1, –5) and (4, 5). First, find the slope: m = rise / run = 5/10 = 1/2.
Then the equation is y-5=(1/2)(x-4). If (a,1) is on this line, (a,1) must satisfy the given equation. Let y=1 and solve for x:
1-5 = (1/2)(x-4) Mult both sides by 2 to get -2 = x-4. Then x = -4+2 = -2
So (-2,1) is also on the line.</span>
