Answer: 3
Step-by-step explanation: y=-2, also y=-2x+4. Therefore, we got a equation: -2=-2x+4. You then minus 4 from both sides of the equation and you will get -6=-2x. You then solve for x by dividing -6 by -2, you get x=3
For this case we must simplify the following expression:
We eliminate the parentheses taking into account that:
We add similar terms taking into account that:
Equal signs are added and the same sign is placed.
Different signs are subtracted and the major sign is placed.

Answer:
The friend's claim is not correct
Step-by-step explanation:
we know that
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal yo -1)
Example
A given line has a slope of ---> (is less than 1)
the slope of the line perpendicular to the given line is equal to
substitute
so
the perpendicular line don't have a positive slope
therefore
The friend's claim is not correct
