Question

Steven works at a large home appliance store. He earns a base salary of $20,000 plus commission which can be modeled by the equation y = 0.1x + 20,000. What is the meaning of the y-intercept in the equation?

Answer 1

It is his base salary

Answer 2

y-intercept in the equation is, A base salary.

Explanation:

Slope intercept form:

The equation of line is given by:

`y = mx+c` ....[1]

where, m is the slope and c is the y-intercept.

Given the equation:

y = 0.1x + 20,000

where, x is the number of units and y is the salary

Comparing with equation [1] we have;

m = 0.1

y(0)= c = 20000

Therefore, the meaning of the y-intercept in the equation is, a base salary.
