Explanation:
Our straight line has the same gradient as that of the line,

Dividing each term by 2,

Now this equation is in the form
so the gradient of this line is 5/2.
So the gradient of our straight line is,

Given our straight line passes through the point,

The equation of a straight line passing through a point
and having gradient
is given by,

This form of equation of a straight line is called point - slope form.
By this point - slope form, the equation of our straight line will be given by,





This is the equation of our straight line, written in the form
