Answer:
y=(-5/2) x -7
Step-by-step explanation:
y=mx+b
m=(-5/2)
To find b:
3=(-5/2)times"x" + b
3=(-5/2)times(-4) + b
3= 10 +b; b=-7
y=(-5/2) x -7
Well its pretty hard let me see its 8 by cm and 27 by aera
Answer:
c
Step-by-step explanation:
The length can be found using the Pythagorean Theorem...
c^2=a^2+b^2 and in this case:
d^2=(dx^2)+(dy^2)
d^2=(3-7)^2+(12-9)^2
d^2=-4^2+3^2
d^2=16+9
d^2=25
d=5
So the length of AB=5 units.
