Answer:
x= -3/4 + y/4
Step-by-step explanation:
Move all terms that don't contain
x to the right side and solve.
Answer:
x=4 y=0
Step-by-step explanation:
3x+5y=12
-(x-3y=4)
3x+5y=12
3(-x+3y=-4)
3x+5y=12
-3x+9y=-12
14y=0
y=0
Then, substitute the y into the equation to find x
x-3(0)=4
x=4
Answer: 
Step-by-step explanation:
We can rewrite the left hand side as a perfect square, more specifically

So, taking the square root of both sides,

Answer:
1. y = -0.6x + 5.4.
2. The entered points belong to a vertical line. There is no slope.
Equation: x = 6
3. y = 0.16667x + 5.5.
4. The entered points belong to a vertical line. There is no slope.
Equation: x = -8.
