(y1 - y2) / (x1 - x2) = slope
(-1 - 3) / (4 - 2)
-4 / 2
<em>-2</em>
Hope this helps! :)
Answer:

Step-by-step explanation:
1) Solve inside the parentheses.

2) Simplify (0.5 × - 0.6 ) to -0.3.

3) Simplify -0.3 × 0.4 to -0.12.

<em><u>Therefor</u></em><em><u>,</u></em><em><u> </u></em><em><u>the</u></em><em><u> </u></em><em><u>answer</u></em><em><u> </u></em><em><u>is</u></em><em><u> </u></em><em><u>-0.12</u></em><em><u> </u></em><em><u>.</u></em>
Answer:
x + y + z = 180 (this is the first equation)
w + z = 180 (this is the second equation)
Now, rewrite the second equation as z = 180 - w and substitute that for z in the first equation:
x + y + (180 - w) = 180
x + y - w = 0
x + y = w
Step-by-step explanation:
Brandon's rectangle:
Length = 8.75 x 1.5 = 13.125 inches
Width = 6 x 1.5 = 9 inches
If you need the area and perimeter then here:
Area = 13.125 x 9 = 118.123 inches square or sq in.
Perimeter = 2 x (13.125+9) = 44.25 in
