The equation of a line in the slope intercept form is expressed as
y = mx + c
Where
m represents slope
c represents y intercept(This is the point where the line cut across the y axis.
The first step is to find the slope. The formula is
Slope, m = (y2 - y1)/(x2 - x1)
From the given points on the graph,
when x1 = 0, y1 = 2
when x2 = 3, y2 = 4
m = (4 - 2)/(3 - 0)
m = 2/3
Looking at the graph, at the point where the line cuts the y axis, y = 2. Thus, c = 2
We would substitute m = 2/3 and c = 2 into the slope intercept equation. Thus, the equation of the line is
y = 2x/3 + 2
The correct option is A
