Question

What is the slope of a line parallel to the line with this equation:

Answer 1

The slope of two parallel lines are equal.

Let us find slope of given equation.

The general slope intercept form is given by :

$y=mx+c$

where m is slope

our equation is :

$5x-15y=30$

Now we have to convert our equation into slope intercept form.

let us try to isolate y on the left side.

taking 5x to the right side we have ,

$-15y=-5x+30$

dividing both sides by -15,

$y=\frac{x}{3} -2$

coefficient of x is slope,

so slope is 1/3

slope of line parallel to it is also same that is 1/3 .

Correct option is D.
