Question

Need help don't know how to solve

Answer 1

option A:

3/2

Explanation:

let's take any two co-ordinates from the graph:

x1, y1 = 2, 3

x2, y2 = 4, 6

equation of the line is, y = mx + c

where slope, m = y2 - y1 / x2 - x1

= 6 - 3 / 4 - 2 = 3/2

thus, constant of proportionality, m = 3/2
