Answer:
If you plot these points you will see that the base is 6 (distance from E to F, count the squares).
The height will be 6 ( distance from line EF to D, again count the squares).
Using the Area formula you get A = 1/2 (6) (6) = 18
-- Add 1 to each side.
-- Then subtract 'x' from each side.
-- Finally, divide each side by 4, and the answer will jump out at you.
<span>This is asking for a linear function. The base pay is $150, so even if she sells nothing, she cannot be paid less than $150. Because of this, we make that out y-intercept. The number of appliances sold is a variable, so we make that the "X" and multiply that by the amount made ($45) on each additional item sold. You then follow the Order of Operations (PEMDAS) to make your equation.</span>
