Question

Choose the equation that represents the graph below.

Answer 1

Here are the options :y = –1
x = 1
x = –1
x = 0

Answer 2

x = -1

Answer 3

How were you able to find that?

Answer 4

it's the vertical line go through (-1,0), basically, at any y, x will be always -1 so the function doesn't depend on y value. s, x= -1

Answer 5

So as a slope would it be considered undefined?

Answer 6

yes, the slope= change in y/change in x, the change in x is 0, so a number/0 = undefined

Answer 7

thank you :)
