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
Answer:
Slope is 5/2
Step-by-step explanation:
5x-2y=10
subtract 5x from both sides
-2y=-5x+10
Then you divide -2 on both sides
y=5/2x-5
Which will result 5/2 as the slope
