Answer: -1
Step-by-step explanation: So if the Temperature last night was at -3o C and now it is -4o C it went down by 1 but dont forget the negative symbol.-1
you can think like this: -3-4=-1
It's directly proportional, so
m=kw
Find the value of k
900=k(18)
k= 50
Answer: m=50w
Answer:
you given me only 25 point
y -y1= m(x-x1) is in point slope form
y --9 = -2 (x-10)
y+9 = -2(x-10)
Answer:
2/7
Step-by-step explanation:
gradient y²-y¹/x²-x¹=4-2/4-(-3)
=2/7
{Taking (x¹,y,¹)=(-3,2)
and(x²-y²)=(4,4)
