Write the equation of the line that passes through the point (3, -1) and is parallel to the line x - 3y =9

y+1=1/3(x-3)

Step-by-step explanation:

x-3y=9

3y=x-9

y=1/3x-9/3

y=1/3x-3

y-(-1)=m(x-3)

y+1=1/3(x-3)

Remember that parallel means same slope.

80 the answer is 80

step-by-step explanation:

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
