The property displayed here is the distributive property.

If you have a variable or unknown number inside or outside of parentheses, you can distribute it to each term and add the terms together, and it will remain true.

Example:

4(x + 5)

After distributing, it'll look like this:

4x + 20

how many solutions does the graph above show? a. one b. none c. infinite

dmitriy555 [2]

Answer:

infinite

Step-by-step explanation:

The line can be represented by the equation y=-2/3x-2 since there are no other lines it would be infinite. if there was a line with the same slope and a different y-intercept the answer would be none as the lines never intersect. for the equation there are ifinitly many!

for example any point that that lone touches is a solutions so there is not one but many answers.
