y = x means that the line is going 1 value of x for every 1 value of y.
The intersection would be at the (0,0).
However, y = x+2 would have a intersection at (0,2) when y-axis have the value 2. The slope doesn't increase, because the derivative of both slopes gives us y = 1.
Therefore, the line shifts up 2 units.
Hope you understood!
Good luck ;)

First you find how much you need to make
130 - 5 = 80
now simply divide that by the amount earned per hour
80 ÷ 8 = 10
The answer to the above question can be explained as under -
We know that, the sum of angles of triangle is 180°.
So, vertex angle plus base angles are equal are equal to 180°.
Let the vertex angle be represented by "v" and base angles be represented by "b".
Thus, v + b + b = 180°
So, v + 2b = 180°
Next, the question says, the vertex angle is 20° less than the sum of base angles.
Thus, 2b - 20° = v
<u>Thus, we can conclude that the correct option is A) v + 2b = 180°, 2b - 20° = v</u>
