Linear function

What is the equation of linear function passing through points:

a) A (0,3), B (3,0)
b) A (-2,-6), B (3,4)

Correct answer:

a =  0

Step-by-step explanation:


3 = q·0+w
0 = q·3+w

w = 3
3q+w = 0

Pivot: Row 1 ↔ Row 2
3q+w = 0
w = 3


w = 3/1 = 3
q = 0-w/3 = 0-3/3 = -1

q = -1
w = 3
