Question

Which equations represent a linear function? Select two. a. y = x-1 b. y = – 4.5 C. 3x – 4y = 2 d. 5x2 = 10y e. y = 1/2x2 +6

Answer 1

`\begin{gathered} a)y=x-1 \\ c)3x-4y=2 \end{gathered}`

Step-by-step explanation

a linear function must have

dependent and independent variables, ( y and x in this case)and the exponent of the independent vairable must be 1, so

Step 1

Check

a)

`a)\text{ y=x-1}`

this is a linear function

b)

`y=4.5`

this is not a functin, this expression has not x

c)

`3x-4y=2`

this functin has x and y, and the exponent of x is 1, so, this is a linear function

d)

`5x^2=10y`

this function has x and y, but the exponent is 2, so this is not a linear function

e)

`y=(1)/(2)x^2+6`

this function has x and y, but the exponent is 2, so this is not a linear function

i hope this helps you
