Answer:
[tex]m = 1[/tex] (The slope of the line perpendicular to y = -x + 5 is supposed to be 1.)
Step-by-step explanation:
The slope of a line that is perpendicular to another line is: [tex]-(m^-^1)[/tex], where m is the slope of the line.
The slope of a line perpendicular to the line y = -x + 5 will be:
[tex]m = -( -1^-^1)[/tex]
[tex]m = 1[/tex]
Answer:
2 (D)
Step-by-step explanation:
This is a Linear Equation. This equation will show you the y intercept, and slope of a line. In the equation shown, -1 is the coefficient of x, therefore the starting line has a slope of -1. This means that the perpendicular line should have a positive slope, because they must intersect. If it was negative it would become more or less parallel to the original line. This eliminates answers A and B. If C was chosen, the two lines would intersect but they would not be perpendicular. This means the answer is B.
