Find the soluiton
2x+2y=16
3x-y=4
x+y=8
<u>3x-y=4+</u>
4x=12
x=3
3(3)-y=4
9-y=4
y=5
(3,5)
test them to see if get true statment
obviously the first equatons of 1,2,4 work
1 doesn't work
2, works
4. doesn't work
2 is the same as the first except both euations are just doubled
answer is 2

Answer:
The answer is
<h2>

</h2>
Step-by-step explanation:
To find the equation of the line given a point and slope we use the formula
<h3>

</h3>
where
m is the slope
( x1 , y1) is the point
From the question the point is (0 , 3) and slope is - 6
Substitute the values into the above formula and solve
That's
<h3>

</h3>
We have the final answer as
<h3>

</h3>
