Question 3(Multiple Choice Worth 1 points) (04.02 MC)
The equation of line LM is 5x - y = -4. What is the equation of a line perpendicular to line LM in slope-intercept form that contains point (-3, 2)?
Oy = 5x + 13
7
X +
5 5
Oy=-*
Oy=1 / X - 1 / 3
7
Oy = 5x - 17

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

step-by-step explanation: you take each of the numbers and divide by the amount then you take the range

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

to determine the unit cost your would divide the total cost by the number sold.
