No.
-----------
It is a straight line with gradient -A/B and intercept C/B.
5
a straight line (the Y-axis of a coordinate plane)
The graph of [ y = -3x ] is a straight line, through the origin, with slope of -3 .
It cannot.
A linear equation ?
The graph of y = x - 8 is a straight line. The slope of the line is 1, and it intersects the y-axis at the point y = -8.
[ 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.
3
The is a straight line parallel to the y-axis with an x intercept at -3.
The equation has no slope. The graph of the equation is a straight line with a slope of -1 .
