Is this function linear or nonlinear?

y=3x−5y=3x−5

nonlinear

linear

I believe the correct answer from the choices listed above is the first option. The function given as y=3x-5 is a linear function where y varies directly with x. Linear functions are those whose graph is a straight line. A linear function has the following form. y = f(x) = a + bx.
Hope this answers the question. Have a nice day.

Hello there.

Is this function linear or nonlinear?

nonlinear

Step-by-step explanation:

Use triangle congruency:

BC=EC, AC=DC - Given

m∠DCE = m∠ACB because they are vertical angles

Therefore ΔABC ≅ ΔDEC because of Side-Angle-Side congruency

AB=DE because corresponding parts of congruent triangles are also congruent (CPCTC)
