If the graphs of the linear equations shown below are perpendicular, what is the value of a?
y = 3x +8
2y = ax - 5

Step-by-step explanation:

We are given the lines, and . For the latter equation, we can isolate the variable y to have the same format as the first. We want to create a y=mx+b equation where m represents the slope of the line. We now have the equations:

and

The definition of perpendicular lines is that their slopes must be the negative reciprocal of each other. Thus:

I hope this helps! Let me know if you have any questions :)

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
