Answer:
= -3
Step-by-step explanation:
Find 2 points
(-2, 4) and (1,-5)
We can use the slope formula
m = (y2-y1)/(x2-x1)
= (-5-4)/(1 - -2)
= -9/(1+2)
= -9/3
= -3
Answer: l = P/2 - w
Step-by-step explanation:
Perimeter formula for rectangle :
P = 2( l + w )
We have to write l in terms of P and W.
P/2 = ( l + w)
P/2 - w = l
Now, flip the equation and you'll get :
l = P/2 - w
10/-5 =2/-1 = -2 (A) is the answer
3 by 21 because 1/4 of 12 is is 3
