Quick Q&A Before You Revise
How many solutions does a linear equation in two variables have?
Infinitely many. Each choice of a value for one variable gives one value of the other, and every such pair is a solution corresponding to a point on the line.
Why is the graph of ax + by + c = 0 always a straight line?
Because as x changes by a fixed amount, y changes by a fixed amount (the ratio is constant), which is exactly the property of a straight line.
Is x = 5 a linear equation in one variable or two?
It depends on context. On the number line it locates one point. In the Cartesian plane it is treated as 1·x + 0·y = 5 and its graph is a vertical line.
How many points are needed to draw the graph of a linear equation?
Two points are enough to fix a line, but it is good practice to plot a third point as a check that all three are collinear.
