If B=0, then the graph does not depend on the value of y. This is a vertical line at x = C/A
ax + by = cThe graph if that equation is a straight line whose slope is (-a/b)and whose y-intercept is (c/b).
A linear equation ?
[ Ax + By = C ] If 'A', 'B', and 'C' are numbers, then the graph is always a straight line, and the equation is a "linear" one.
The graph of the first form passes through the origin while the second does not - unless c = 0.
Ax + B = Bx + C Ax - Bx = (C - B) x (A - B) = (C - B) x = (C - B) / (A - B)
ax + b = 15 or ax + b = -15
y = (c - Ax) / (B)
2x - 13x + 42 = x +ax + b a + b = 2(x - 6.5x + 21) = 34 = a + b
Solve the equation for y. This will give you an equation similar to y = ax + b, where a is the slope, and b is the y-intercept.
A linear equation.
