Question

Which equation represents a linear function? A) y = |x| B) y = x2 C) y = -3x3 D) y = 1 4 x

Answer 1

linear means the highest exponent on the placholder is 1
it is also just a straight line

y=|x| is like y=(√x)², it is 2 straight lines

B. y=x², exponent is 2 so no

C. y=-3x³, exponent is 3, so no

D. y=1/4x, yep


D is the answer

Answer 2

A linear equation is an equation in which each term has at max one degree. The equation which represents a linear function is y=(1/4)x.

What is a linear equation?

A linear equation is an equation in which each term has at max one degree. Linear equation in variables x and y can be written in the form y=mx+c.

Linear equation with two variables, when graphed on the cartesian plane with axes of those variables, give a straight line.

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

Hence, The equation which represents a linear function is y=(1/4)x.
