A graph of a non-vertical straight line is a: O A. linear function.
O B. nonlinear function.
O c. non-function.
O D. exponential function graph.

y=mx+b

step-by-step explanation:

m slope

b y-intercept

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i

no ,sorry if you needed it but you can ask and try to see if any one will anwser ,

step-by-step explanation:

by good luck mark me as brainliest

have a nice day
