Question

When graphing the following equations, which one will be a straight line?
A.
y = x^2 + 2
B.
f(x) = 2/3x + 1
C.
y = |x + 4|
D.
x^ + y^ = 1

Answer 1

A

Answer 2

Oh, I thought when dealing with x squared , you will see a curve?

Answer 3

ya x^2 is a parabola

Answer 4

it would be B because it is a linear equation

Answer 5

thats what I think too, but y = |x + 4| is my other choice and so I am confused again

Answer 6

since it is an absolute value the graph would loook like

Answer 7

thus not being a strait line

Answer 8

do you understand why?

Answer 9

V" is the result of the negative absolute values becoming positive?

Answer 10

if B) is straight line is the slope m= 2/3 ? yes or no?
so that f(x) = (2/3)x + 1 ? yes ?

Answer 11

thankyou

Answer 12

not a problem
