Simplified, their slopes multiply to -1.
What that means is that if there's a equation
, if a line is perpendicular , that line's m value multiplied by this line's m value equals -1. For example, if m=1/4 for one value, the first thing we do is make it negative to get -1/4. Next, we switch the numerator and denominator to get -4. If there is a number like 5, the fraction of it is 5/1 (since 5 divided by 1 is 5) and the reciprocal (or the numerator and denominator switched) is 1/5. This also applied to y=mx+b.

Given the equation of the line :
To find the slope convert the given equation to the slope - intercept form
which is like:
where m is the slope
So, solve the given equation for y:
It is on point (1,10). This means the snake population was at 10 after one year.
