Answer:

Step-by-step explanation:
To find the slope you do y1-y2/x1-x2
To find the y intercept you look at when x is zero what is y.
Equation is y=-1/2x -2
Answer:
z = -166
Step-by-step explanation:
1. Subtract 3 from both sides to get z/2 = -83
2. Multiply 2 by both sides to get z = -166
z = -166
The angles inside a trapezoid add up to equal 360 degrees
X = 360-90-90-75 = 105 degrees.
Answer:
We end up with our original number
Step-by-step explanation:
Let x be our number
We increase by 100
increase = old number * 100%
increase = x*1
increase = x
New number = old number + increase
= x+x
=2x
Now we decrease by 50%
decrease = number *50%
= 2x*.5
=x
Final number = new number - decrease
= 2x-x
=x
