Find the solution of system of equation y= x-4 y=4x+2

One line passes through (-7,-4) and (5,4) . another line passes through the point (-4,6) and (6,-9)

Recall that the owner of a local health food store recently started a new ad campaign to attract more business and wants to know if average daily sales have increased. historically average daily sales were approximately $2,700. the upper bound of the 95% range of likely sample means for this one-sided test is approximately $2,843.44. if the owner took a random sample of forty-five days and found that daily average sales were now $2,984, what can she conclude at the 95% confidence level?
