Solve slope and y-intercept.

Slope: -2/1

Y-intercept: (0,0)

Step-by-step explanation:

The equation for slope is:

We can plug in any x, y pairs from the table into the equation. For this, let's use (-5, 10) and (-3, 6)

The equation for a line is...

y=mx+b

m: slope

b: y-intercept

We can plug in a x, y pair and the slope into the equation to solve for the y-intercept:

y=mx+b

10=(-2)(-5)+b

10=10+b

b=0

Therefore the y-intercept is (0,0)

f is the midpoint of

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
