Write an equation of the direct variation that includes the given point (-8, -4)
Direct variation is y= kx for some constant k
Find k using the point (-8,-4)
y=kx
(-4)=k(-8) substitution
-4/-8=k(-8/-8) division property
1/2=k
equation of direct variation is y=1/2k
Move the decimal to the right 8 places
Answer:
2
Step-by-step explanation:
Since x=-2
-2+3y=4
Add 2 on both sides
3y=6
Divide 3 on both sides
y=2
