The equation contains variables which are only raised to the first power.
Ax + By = C By = -Ax + C y = (-A/B)x + C/B
It is: 3x2+6x-11 = 0
It is a straight line with gradient -A/B and intercept C/B.
The graph of the first form passes through the origin while the second does not - unless c = 0.

A linear equation ?
It is a straight line with gradient -A/B and intercept C/B.
Ax + B = Bx + C Ax - Bx = (C - B) x (A - B) = (C - B) x = (C - B) / (A - B)
The graph of the first form passes through the origin while the second does not - unless c = 0.
ax + b = 15 or ax + b = -15
2x - 13x + 42 = x +ax + b a + b = 2(x - 6.5x + 21) = 34 = a + b
a function
A linear equation.
x = -c/(a+b), provided a+b is not 0
