Yes, y = -4x + 3 is a linear equation.
Yes, y = 4x + 7 is a linear equation.
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
It is: 6
No. It is linear. The giveaway here is the lack of an exponent.
the linear relationship is up four over one.
The two equations are linear.
You cannot solve one linear equation in two variables. You can express y in terms of x but that is NOT solving for y.
