Question

x - 3y = 15Use the choices below to determine the type of function above-Quadratic-Exponential-Linear-none of these

Answer 1

In a quadratic equation, the variable x must be raised ti a power of two, this is not our case, since x is not raised to any power.

Linear equations has the form:

y=mx+b, let's arrange our equation to see if we have a linear equation

x-3y=15

by adding 3y in both sides:

x-3y+3y=15+3y

we can cancel 3y in the left side, then we have:

x=15+3y

subtracting 15 from both sides

x-15=3y

dividing by 3 in both sides:

$\frac{3y}{3}=y=\frac{x-15}{3}=\frac{1}{3}x-\frac{15}{3}=\frac{1}{3}x-5$

as we can see, our equation fits into the form of linear equation y=mx+b, where m=1/3 and b= -5
