<u>First, find the perpendicular slope</u>
y = 0.3x + 6 ⇒ m = 0.3 = 
perpendicular slope = 
<u>Next, input</u> the point (x₁, y₁) and slope (m) into the Point-Slope formula
y - y₁ = m(x - x₁)
y - (-8) =
(x - 3)
y + 8 =
+ 10
y =
+ 2
X - 5 <= -2
x <= 3
This is saying, x is less than or equal to 3., so take a filled dot, put it on 3, then draw a line from it towards the left
There you go... a. 10
If we add x to both sides, we get rid of the x on the right side which leaves us 1/2x + 2 = 7. (1/2=0.5)
Then if we substract 2 from both sides, we will get 1/2x = 5
If half of x = 5, then the whole of x = 10.
