Find the slope of the line that contains (3, −6) and (−1, −9).

You use the slope formula:

m = y₂-y₁ / x₂-x₁

And you plug in the points into the formula.

m = -9 - (-6) / -1 - 3

m = -9 + 6 / -1 - 3

m = -3 / -4

m = 3/4

constants mean the stopped points or the points on a graph that nothing is changing, hope this

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
