A graph has number of days on the x-axis and number of canned goods on the y-axis. A line goes through points (2, 699) and (8, 321). Nicholas volunteers at a local soup kitchen and he notices how quickly the kitchen is going through its stock of canned goods. Below is the graph representing the data Nicholas found.

Find the slope and y-intercept of the line.

How do I solve this.

Slope:-63

Y-intercept: (0,825)

Step-by-step explanation:

Slope= y2-y1 ÷ x2-x1

321-699 ÷ 8-2

-378 ÷ 6 =-63

Y-intercept:  

y=-63x+b

to get b (y-intercept) plug in one of the points and solve.

​

699=-63(2)+b

699=-126+b

699+126=-126+126+b

699+126=0+b

825=b

answer: 1 + 1 = 11

step-by-step explanation:

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
