I used geogebra for this. I hope this helps
It is true that if two variables are directly proportional then their graph is a linear function.
<h3>How to determine the true statement?</h3>
The highlights in the statement are given as:
- Two variables
- Direct proportion
- Linear function
The equation of a directly proportional graph is represented as:
y = kx
Where k represents the constant of variation
The equation y = kx is a linear function and k is the slope
Hence, it is true that if two variables are directly proportional then their graph is a linear function.
