Question

Find the solution for the linear equation 3x-y = 4 which represent a point on

a)The x axis
b)The y axis

Answer 1

The equation of a line represents the relationship between two variables. If we know one of the variables (x or y) then we can find the other variable.

a) A point on the x-axis means that y=0. Put y=0 in the equation and solve for x. x=4/3

b) A point on the y-axis mean that x=0. Put x=0 in the equation and y=-4.

You can now use these points to draw line on a cartesian plane. Take a look at the attached photo.
