Hey there!
Let's go through all of our options.
A) It's defintely not curved; it's written in slope intercept form and is indeed a straight line.
B) Yes, the graph is a straight line. Although it's at an angle, it has no curves or flaws, and is completely straight.
C) The graph is not vertical. It has a y intercept and slope and therefore isn't. That's because it has a rate of change, and it crosses the y axis at some point depending on the slope, or rise over run. Vertical lines really don't have that.
D) Yes, the graph is a function. This is because it does not have two x values for one y, and does not fail the straight line test, which states that you can place a straight line anywhere on the graph and it can only go through one point.
E) This is false. If we put in -5 as our input, we add 1 and get -4, which is a negative output. Your output here depends on the input you put in, and the sign usually remains considering it's +1.
F) This graph does not pass through the origin. This is because the origin has a point at 0,0 and since it's x+1, it would be 0,1 instead because your output is adding one to that 0.
Hope this helps!
        
                    
             
        
        
        
What i am supposed to do with that date?dance.
        
             
        
        
        
I would say the x intercept is (6,0) and the y intercept is (4,0)
        
                    
             
        
        
        
Answer:
D. Batch 5. 
Step-by-step explanation:
The batch should have the same proportion of blue to white to yellow. 
In Batch 1, there are two parts of blue, 1.5 parts of white, and 1 part of yellow. 
In Batch 5, there are four parts of blue, 3 parts of white, and 2 parts of yellow. 
4 / 2 = 2
3 / 2 = 1.5
2 / 2 = 1
Since the proportions are equal to those found in Batch 1, D. Batch 5 will create the same colors as the first batch. 
Hope this helps!
