1) The answer is B because it goes through the cluster.

2) Now find the slope and the y intercept.

The slope = 1
Y intercept, where it croses y = 2

y = 1x + 2

3) Look where x = 50, and find y.
x = 50, y = 10

Answer: 10

4) The slope is 10, find two points on the line and calculate
m = y2 - y1/x2 - x1
m = 10

Now find where it crosses, this one is easy, it's 50.

Answer: y=10x+50

the linear model would be the line of best fit
it is the line that represents the average of the points or the line that represents the majority of them equally

so the asnwer would be B since it goest thorugh the middle of the points in teh direction tha tsems right




y=mx+b
m=slope=rise/run
b=y intercept or when x=0

it seems to go up 1 unot for 1 unot it goes to the right sl slope is 1/1=1
y=1x+
x is zero when y=2
y=1x+2





so look at the variabel M line and see where it matches the variable N line
looks to be at 10



slope=(y2-y1)/(x2-x1)
pick 2 points
y is up
x=right

so somepoints are
(0,50) and (20,250)
x1=0
y1=50
x2=20
y2=250
(250-50)/(20-0)=200/20=20/2=10/1=1
y=10x+b
find where x=0
y=50
y=10x+50



so the answers are

B
y=x+2
10
y=10x+50
