Question

Describe the fines below as parallel, perpendicular, or neither. 2x-5y = 25 and y= 2/5x+3

Answer 1

Here, we want to check if these lines are perpendicular, parallel or neither

Firstly, we need to understand the general form of the equation of a straight line

The general equation is;

`y\text{ = mx + b}`

where m is the slope of the line and b is the y-intercept

While the second equation is in the general form already, the first equation is not in the general form

Thus, what we have to do is to write it in the general form

Mathematically, we can have that as follows;
