Answer:
Option C. is the correct option.
Step-by-step explanation:
The given line in the graph passes through two points (0, 3) and (3, 7).
We have to find the equation of the line.
Since y = mx + c is the standard equation of a line
where m = slope of the line
c = y - intercept
Slope of a line m = [tex]\frac{(y-y')}{(x-x')}[/tex]
Now we put the values of x and y to find the slope of this line.
m = [tex]\frac{7-3}{3-0}=\frac{4}{3}[/tex]
Since (0, 3) passes through the line
3 = 0 + c
c = 3
Equation of the line will be
[tex]y=\frac{4}{3}x+3[/tex]
Option C. is the answer.
