Does this graph represent a function? Why or why not?

D

Step-by-step explanation:

The answer is yes, because it passes the vertical line test.

D. Yes, because it passes the vertical line test.

Step-by-step explanation:

The vertical line test are drawing lines up and down, to see if there are any two points on that graph that hits the same line twice.

i think thats the answer i checked it on google

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
