Aline on the coordinate plane passes through the points (7, -5) and (3, 11). a line that is perpendicular to the first line passes through the points (-3, -9) and (5, n). find the value of n.

Slope of the line passing through (7,-5) and (3,11) =

= -4

As two lines are perpendicular to each other, so when their slopes are multiply by each other, the answer will be -1

so the slope of the line passing through (-3,-9) and (5,n) will be

So will will get a formula below

and the answer will be n=

That’d be 9 years or something

That is right sorry i was gonna answer but i already saw his
