The domain of a graph is: A all of the possible x values
B all of the possible y values
C a set of coordinates that create a function
Da set of coordinates do not create a function

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

could you provide figure.

step by step explanation: when u removing the parentheses and combined them that would be : x+3y-x-y=2y
