Yes, y=3 is a linear function.
In fact, its graph is a horizontal line (parallel to the x axis), because it sets a constant value for y (for all values of x, y=3).
Yes, y = 3+x is linear.
Yes, y = -4x + 3 is a linear equation.
If you already know that x = -3 and y = 5 what linear equations are you wanting to solve?
It equals a simple linear equation in 'y'. Its solution is 7/3 .
y= 2x-3 when y=0 2x=3 x=1.5
Yes.
The rate of change for the linear (not liner) function, y = 2x +/- 3 is 2.
-3
It works out that x = 0 and y = 3

One linear equation in 3 unknowns cannot have an answer.
y = 2x + 3 is LINEAR. It is a straight line graph with a steepness/gradient of '2' ( The 'x' coefficient). The line passes through the y-axis at '3'
