Question

The equation y = x - 3 represents a line perpendicular to y = -x + 3. Is This TRUE or FALSE?

Answer 1

finding somethign perpendicular means teh number before the x is opposite resiprical. the first equation has 1. and the second is -1. TRUE

Answer 2

y1 = x - 3 so m1 = 1
y2 = -x + 3 so m1 = -1

for the two lines to be perpendicular it must satisfy m1 = -1/m2

since 1 = -1/(-1) then yes in fact they are perpendicular.

TRUE.

Answer 3

m2 = -1 ****
