A) y= -3x +3 and the slope is -3

Answer: a)  y=-3x+3

Step-by-step explanation:

The equation of a line passing through a point (a,b) ans has slope m is given by :-

(y-b)=m(x-a)

Similarly, the equation of a line passing through a point (-1,6) ans has slope -3 is given by :-

(y-6)=-3(x-(-1))\\\\\Rightarrow\ y-6=-3(x+1)\\\\\Rightarrow\ y-6=-3x-3\\\\\Rightarrow\ y=-3x-3+6\\\\\Rightarrow\ y=-3x+3

Hence, the correct option is : a) y=-3x+3

A washer and dryer cost a total of $924. The cost of the washer is two times the cost of the dryer. Find the cost of each item.
marshall27 [118]

Answer:

Washer = $616, Dryer = $308

Step-by-step explanation:

When something is twice the cost of something else but add up to be a total number that means 2/3rds is one item and 1/3 is the other.

924 / 3 = 308

308 * 2 = 616

308 + 616 = 924
