A line passes through the points (1,6) and (4,3). What is the y-intercept of this line?
O-9
O-3
O 3
O9

0,9

Step-by-step explanation:

it has to be higher than 1,6, because the lines go down after the y- intercept. Hope that this helps you and have a great day :)

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.
