Question

6. The slope of the line which is perpendicular to a line joining the points (0,0) and (-8, 8) is ​

Answer 1

Answer:

so slope of the line joining the points (0,0) and (-8,8) is

y2-y1/x2-x1

so

8–0/-8–0

=8/-8

=-1

so slope of the line is -1

so in straight lines chapter we all know that if two lines are perpendicular to each other then the product of their slopes is -1

so let the slope of the other line be m

so

-1x m = -1

so m=1

so answer is 1

Answer 2

suppose the given A is x1y1

suppose the given B is X2 Y2

✓0-(-8)+✓ 0-8

answer is 8 or -8
