What is the equation of the line that goes through the points (1,1) and 3,-3)
navik [9.2K]

Answer:

y = -2x + 3

Step-by-step explanation:

[]Let us write an equation in slope-intercept form.

-> See attached

-> Our equation will start out as y = x

[] The slope can be found by taking the change in y divided by the change in x

-> \frac{-3-1}{3-1}=\frac{-4}{2}=\frac{-2}{1}=-2

-> Now our equation is y = -2x

[] The y-intercept, or b, can be found by plugging a point given to us into the equation we have so far.

-> y = -2x + b

(1) = -2(1) + b

1 = -2 + b

3 = b

-> Now our equation is y = -2x + 3, which is our final answer.

Have a nice day!

We have 6 tents for 18 campers each tent holds 2 or 4 campers exactly how many of our tents hold 2
wolverine [178]

Answer:

  3 tents hold 2 campers

Step-by-step explanation:

The given relations can be expressed as a single equation in the number of 2-camper tents.

__

Let x represent the number of 2-camper tents. Then the number of 4-camper tents is 6-x, and the total number of campers in tents is ...

  2x +4(6 -x) = 18

  -2x +24 = 18

  -2x = -6 . . . . . . subtract 24

  x = 3 . . . . . . . divide by -2

Exactly 3 tents hold 2 campers.

_____

<em>Additional comment</em>

The other 3 tents hold 4 campers.

Another way to consider this is to assume that all tents hold 2 campers, and then realize there are 18 -6×2 = 6 campers left over. If these are placed 2 per tent, then there will be 6/2 = 3 tents with 4 campers. The remaining 3 tents will have 2 campers.
