Answer:
y = -4x +9
Step-by-step explanation:
The same slope-intercept equation can be used, but with a different y-intercept. That new y-intercept can be found from the given point (x, y) using the formula ...
b = y -mx
b = 5 -(-4)(1) = 9
So, the equation with the new y-intercept is ...
y = -4x +9
"In Store A, a book that regularly sells for $24.99 is on sale at 15% off. In Store B the same book regularly sells for $27.99 and is on sale at 25% off. Which store sells the book for the lower sale price?"
"the choises are A Store A; Store A’s sale price is $18.74 and Store B’s sale price is $23.79. B Store A; Store A’s sale price is $18.74 and Store B’s sale price is $20.99. C Store B; Store A’s sale price is $21.24 and Store B’s sale price is $20.99. D Store B; Store A’s sale price is $21.24 and Store B’s sale price is $23.79."
15% of 24.99 is 3.7485.
24.99 - 3.7485 = 21.2415
25% of 27.99 is 6.9975
27.99 - 6.9975 = 20.9925
