Pls answer this one and I will mark your answer brainlist

Answer:
A
Step-by-step explanation:
Partial Variation is a relation that is in the form y = mx+b. The graph of y = mx+b is a straight line with the slope of m and a y-intercept of b. The line y = mx+b does not pass through the origin. The relation y = mx +b represents partial variation because the value of y varies partially with the value of x.
