Please answer ASAP, the best correct answer will get brainliest! Tanica drew a line of best fit on a scatterplot, as shown below.

The equation of the line is y almost-equals negative 1.02 x + 7.09. Using the line, she predicted that when the value of x is 0.5, the value of y will be approximately 7.6. What was her mistake?
A. She drew the line of best fit incorrectly.
B. She used the line of best fit to predict y for an incorrect value of x.
C. She forgot the minus sign before the first term on the right side of the equation when she predicted y.
D. She plugged 0.5 into the equation for y instead of x and actually predicted x instead of y.

How can you tell when x and y are not directly proportional?

Someone answer asap for ! a discount store’s prices are 25% lower than department store prices. the function c(x) = 0.75x can be used to determine the cost c, in dollars, of an item, where x is the department store price, in dollars. if the item has not sold in one month, the discount store takes an additional 20% off the discounted price and an additional $5 off the total purchase. the function d(y) = 0.80y - 5 can be used to find d, the cost, in dollars, of an item that has not been sold for a month, where y is the discount store price, in dollars. create a function d(c(x)) that represents the final price of an item when a costumer buys an item that has been in the discount store for a month. d(c(x)) =

In the diagram, gef and hef are congruent. what is the value of x
