Question

Which equation represents a linear function

Need Now


X=3
Y= -3x + 10
Y=3x^{2} +1
Y=16 over X

Answer 1

Option B) y=-3x+10 is correct

The equation y=-3x+10 represnts a linear function.

Explanation:

To verify that which equation represents a linear function:

Given y=-3x+10

Linear functions are functions whose graph is a straight line. A linear function can be written as y=f(x)=a+bx where x is the independent variable and y is the dependent variable.It has only one independent and dependent variables.

It can be written as y=10-3x

Given equation is also in the form of linear function where a=10 and b=-3

Therefore Option B) y=-3x+10 is correct

The equation y=-3x+10 represnts a linear function.
