(y-y0)/(x-x0)=slope
so (85-76)/(2-(-11))=9/13
Answer:
PQ ≈ 14.14 units
Step-by-step explanation:
calculate the distance d using the distance formula
d = 
with (x₁, y₁ ) = P (0, 4 ) and (x₂, y₂ ) = Q (10, - 6 )
PQ = 
= 
= 
= 
≈ 14.14 units ( to 2 dec. places )
Answer:
Step-by-step explanation:
I will assume that you meant: (-3/7)(y-28) - (1/21)y
Using the distributive property of multiplication, we get:
(-3/7)y + (3/7)(28) - (1/21)y
Let's first reudce the middle term. We get: 12
Then we have:
(-3/7)y + 12 - (1/21)y
Here there are two different denominators. We must combine the y terms. The LCD here is 21. Multiplying (-3/7)y by 21/21, we get the equivalent:
-9y
------ + 12 - (1/21)y
21
or:
-9y 21
------ + 12----- - (1/21)y
21 21
Combining the y terms, we get (-10/21)y:
-10y 252
------- + -------- = (1/21)(-10y + 252)
21 21
