Plug in the coordinate (7, 10) into the equation so
10 = 1/2 (7) + b
You use b and not - 9 because you’re making a complete different equation so solve for b
10 = 1/2 (7) + b
Multiply 1/2
10 = 3.5 +b
Subtract 3.5 on both sides
6.5 = b
Plug b (6.5) back into the equation but flip the slope as a negative reciprocal because it’s asking for a perpendicular line so
y = -2 + 6.5 (your equation)

Angles on one side of a straight line always add to 180°.

Look at the picture.

a = 180° - 134° = 46°
b = 180° - 130° = 50°

In a triangle, the three interior angles always add to 180°.

a + b + c = 180°

c = 180° - (46° + 50°) = 180° - 96° = 84°

x° = 180° - 84° = 96°


We can see that:
x = a + b
