Add 3 and 9 together divided by 2 ....u should get 6
Answer:
y = x + 6.
Step-by-step explanation:
y = mx + c where m = the slope of the line and c is the y-intercept.
So here m = 4/4 = 1 and c = 6, so it's:
y = 1x + 6.
You did not include the given line to which your line is parallel to.
Nevertheless, I can explain you how to solve this problem and which the possible solutions are.
1) x-intercept = - 3 = y = 0
The only two equations that include the point (-3,0) are y = x + 3 and y = - x - 3 (you likely forgot to place the negative signs).
You can prove that in this way:
a) y = x + 3
y = 0 => x + 3 = 0 => x = - 3
b) y = - x - 3
y = 0 => - x - 3 = 0 => x = - 3
Then, so far you have two options: y = x + 3 and y = - x - 3.
2) The slope of y = x + 3 is 1 and the slope of y = - x - 3 = - 1 (the coefficient of the x).
3) You know that line whose equation you are determining is parallel to the given line. That means that their slope are the same. So, your next step is to determine the slope of the given line. It shall be either 1 or - 1. Once you have the slope, you will know whether the solution is y = x + 3 or y = - x - 3.
Given equation is y=3x+3 and 
Let's simplify the 2nd equation before we can start graph so that calculation will be easy
multiply both sides by 3 to cancel out fractions
y=3x+3
which is exactly same as the first equation so graph of both will be exactly same and solution will be infinitely many solutions.
y=3x+3 has y-intercept 3 so first point will be (0,3). Slope is 3 so rise 3 unit up then 1 right and graph the new point.
