Two nonvertical lines have slopes m 1 and m 2, respectively. the lines are parallel if and the are unequal; the lines are perpendicular if or

we know that

If two lines are parallel, then their slopes are the same

m1=m2

and the y-intercept is unequal

If two lines are perpendicular, then the product of their slopes is equal to -1

m1*m2=-1  or m1=-1/m2

therefore

the answer is

Two non vertical lines have slopes m1 and m2​, respectively. The lines are parallel if​ m1=m2 and the ​y-intercept are​ unequal; the lines are perpendicular if​ m1*m2=-1 or​ m1=-1/m2.

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine
