Linear equation given as traverse
You need to find
- Coefficient of a straight line perpendicular
- Coefficient of b straight line perpedicular
Coefficient a
We are looking for the inverse of the number of opposite sign
a₁ = - 1/4 ⇔ a₂ = 4
substantiation
a₁ *a₂ = -1
- 1/4 * a₂ = -1
a₂ = -1 * (- 4)
to the model equations we put all the known values
a₂ = 4 P=(-4,3)
x,y
y = ax + b
3 = 4*(-4) + b
we can calculate b , because it is the only unknown
3 = -16 + b
b = 3 + 16 = 19
simple perpendicular
y = 4x + 19
