Linear Relations

Question

x y
4 2
6 3
8 4
10 5
12 6

 

x goes up by +2 each time.

y goes up by +1 each time.

 

For this linear relation, develop the equation for the relation.

Answer 1

m = Δy/Δx

m = 1/2

 

Continue the pattern "backwards" and if x = 0, y = 0. y-intercept ("b") = 0

 

y = x/2
