Yes, y = -4x + 3 is a linear equation.
Yes, it is a linear straight line equation.
It is a linear equation in x. It has a solution, which is x = -5
In the linear equation: y = -4x+4 +4 is the intercept on the y axis -4x is the negative gradient which is sloping downwards from left to right
You cannot solve one linear equation with two variables.
-4x + 4y = 1
It's a simple linear equation in 'x'. It's not true unless x = 3 .
It is: 6
