Yes, 3x = 5y is a linear function.
It is.
3X = 5Y solve for Y Y = 3/5X this is by definition a linear equation solved. You can plat this straight line on a graph.
It is a linear equation with a single variable, y.
Definitely linear In straight line form it is 5y = 2x + 10 y = (2/5)x + 10/5 y = (2/5)x + 2
A single linear equation in two variables cannot be solved.
5x + 5y = 19x = 3.8 - yory = 3.8 - x
Looks like a linear equation to me, and a ridiculously easy one at that.
x = 3, y = 3
3x + 5y = -1 2x - 5y = 16 Add the two equations: 5x = 15 or x = 3 Substitute for x in the first equation: 3*3 + 5y = -1 15 + 5y = -1 5y = -10 so y = -10/5 = -2 The solution is (x, y) = (3, -2)
f(x)= (4 - 5y)/8 f(y)= (4 - 8x)/5
It is a linear equation in two dimensional space. Such an equation defines a line in 2-d
