Question

Write an equation of the line that passes through the points.

(−3, 0), (0, 0)

y=?

Answer 1

Since we need the line to pass through (0,0) it will have the equation y=Ax for some constant A. Since we need the equation to pass through the point (-3,0) we have that 0=-3A and hence, A=0. Therefore, the required line is given by the equation y=0 which is the x-axis.
