How do you determine whether a relationship represented as as graph is linear or nonlinear

If sin(x) = 0 and cos(x) = 1, what is tan(x)?

Choose the equation below that represents the line that passes through the point (2, 4) and has a slope of 3. a) y − 4 = 3(x − 2) b) y − 2 = 3(x − 4) c) y + 4 = 3(x + 2) d) y + 2 = 3(x + 4)
