Answer:

\boxed{y=-2x+5}

Step-by-step explanation:

The equation in slope-intercept form is given by:

y=mx+c

where m is the slope and c is the y-intercept.


The given line passes through so many points. We can use any two these points to find the slope of the line.

The line passes through (x_1,y_1)= (1,3) and (x_2,y_2)=(2,1).

The slope is given by;

m=\frac{y_2-y_1}{x_2-x_1}.


\Rightarrow m=\frac{1-3}{2-1}.


\Rightarrow m=\frac{-2}{1}=-2.

The y-intercept from the graph is c=5


Our equation finally becomes;

y=-2x+5

Answer:

y = -2x+5

Step-by-step explanation:

We have two points so we can find slope

(0,5)  and (1,3)

m = (y2-y1)/(x2-x1)

   =  (3-5)/(1-0)

   =-2/1

  The slope = -2

We know the y intercept is 5  (This is the point where it crosses the y axis)

The slope intercept from is

y= mx+b  where m is the slope and b is the y intercept

y = -2x+5

It's candy time! Suppose 5 friends go out candy collecting. Starting out, Ms. Gleason gave each of them 12 pieces of candy. Then
sdas [7]

Answer:

6 hours

Step-by-step explanation:

First, since they all collected 510, you divide 510 by 5, to figure out how much each person got.

You then know that each of them got 102 candies, so now, you subtract 12 from from 102, since the teacher gave them that much in the beginning.

You're left with 90, so last step is to divide 90 by 15, since they collect 15 every hour, which you get left with 6. Meaning they collected candies for 6 hours
