Question 5
Mice21 [21]

Answer:

The missing value is 2

Step-by-step explanation:

A direct variation satisfies the equation y=kx.

Since the point (-18, 12) lies on this line, it must satisfy this equation.

\implies 12=-18k

k=-\frac{12}{18} =-\frac{2}{3}

Hence the equation of this line is y=-\frac{2}{3}x

Now we substitute x=-3 to find y.

y=-\frac{2}{3}*-3=2

Therefore the missing value is 2

How do you find the equation of a line if it is like 2x-3y=6?<br> Please show work
tatiyna

Answer:y=2/3x-2

Step-by-step explanation:

you need to get “Y” by itself therefore you subtract 2x on each side you will end up with -3y=-2x+6 then to get “Y” by itself you divide by -3 on both side and since there is a negative 2 on the other side a negative and a negative makes a positive and then you divide the 6 by -3 , that will give you y=2/3x-2
