Answer:
y=10x+9; y=5x+9
Step-by-step explanation:
First of all, answers B and D are wrong because the formula is <em>y=mx+b. </em>So, that leaves us with a and C.
I couldn't find the slope because it was hard to see. try finding a point where it is clear what the points are and do change in y over change in x. I hope this helped at least a bit.
First you need to find the slope of the line using the given coordinates of the two points.
The slope of the line = (1-4)/(4-3) = -3
Then you choose one pair of the coordinates given, either (3,4) or (4,1) , up to you, to find the equation of the line.
If you choose (3,4)
Then
(y-4)/(x-3) = -3
(y-4) = -3x+9
y = -3x+13
If you choose (4,1),
Then
(y-1)/(x-4) = -3
y-1 = -3x+12
y = -3x+13
So, F(x)=-3x+13
C, the sum of the decimals is greater than one, meaning they shade more than one.
5 - 6 = -1
2 + 7 = 9
-1 × 9 = -9
-9 would be the simplified answer.
Hope this helps!
