Can someone give me the correct answer for this.
Minchanka [31]

Answer:

The correct answer is option C that is graph X.

Step-by-step explanation:

Given : 1 sack lunch has 3 sandwiches

x axis = Number of sack lunches

y axis = Number of sandwiches

The coordinate from the given data will be: (1,3)

So, from the given graphs the graph with coordinate point (1,3) is correct. It will also show change in number of sandwiches with respect to change in number of sack lunches.

Which best describes the effect on the x-intercept of the graph of y=34x−3 if the slope is changed to −34
lesantik [10]

Answer:

The last option: The x-intercept becomes negative and the new line intersects the original line.

Step-by-step explanation:

Remember that when finding the x-intercept you set y to 0.

Let's compare the two equations when we solve for x:

0=34x-3          0=-34x-3

1. Add 3 to both sides of the equations

3=34x               3=-34x

2. Divide the coefficients

\frac{3}{34}=x                   \frac{3}{-34}=x

We know that the new slope does not remain the same as stated in the first and third options. In order for two lines to be parallel, the slopes must be exactly the same, so the second option is incorrect. Therefore, the last option is correct.
