EXPLANATION:
To find the value of y when x is equal to 1 I must follow the following steps:
1-Replace in the given equation in the variable x by the value of 1
2.Then I must perform the operation correctly.
The exercise is as follows:
We've got the first number, so now we need the others.
There is 1 possibilty for the first digit, 10 for the middle ones, and 2 for the last one.
1*10*10*2=200

If two lines have the same slope, then they are parallel. Slope is indicated by the number before the variable, in this case, “x”. The line given and “D” have the same number before the variables, therefore the line and “D” are parallel.
