LenKa [72]

Answer:

step 1. y - y1 = m(x - x1). this is the equation given a point and a slope.

step 2. find the slope m. m = (y2 - y1)/(x2 - x1) = (4 - (-4))/(0 - 2) = 8/-2 = -4.

step 3. y - (-4) = -4(x - 2) ; y + 4 = -4x + 8.

10. Solve for z: 2 + 8 - z = -24
iVinArrow [24]

Answer:

The answer is z = 34.

Step-by-step explanation:

1) Simplify 2 + 8 - z to 10 - z.

10 - z =  - 24

2) Subtract 10 from both sides.

- z =  - 24 - 10

3) Simplify - 24 - 10 to -34.

- z =  - 34

4) Multiply both sides by -1.

z = 34

<u>Therefor</u><u>,</u><u> </u><u>the</u><u> </u><u>answer</u><u> </u><u>is</u><u> </u><u>z</u><u> </u><u>=</u><u> </u><u>34</u><u>.</u>
