Answer:

Explanation:

y = mx + b

Take any two points and set up 2 equations with 2 unknowns.

I'll start with the first two

y = 4x + b

410 = 4x + b (1)

440 = 6x + b (2)

Subtract (1) from (2)

440 = 6x + b

410 = 4x + b Subtract

30 = 2x Divide by 2

30/2 = 2x/2

x = 15

440 = 6(x) + b

440 = 6*15 + b

440 = 90 + b

b = 350

Now here is what you found.

Her base salary is 350 dollars

Each television she sells brings her an addition 15.
