Best Line of Fit

Algebra II

Step-by-step explanation:

We can graph the scatter plot and estimate a best line of fit by drawing it in (See Attachment). We can also get the best best of line of fit using your calculator's graphing capacities. The black line is our estimated best line of fit and the red line is the linear regression.

Step 1: Define

Find 2 points from the chart.

Point (1, 2)

Point (7, 7)

Step 2: Find slope m

Simply plug in the 2 coordinates into the slope formula to find slope m

Step 3: Find Equation

We can roughly estimate the y-intercept of the best line of fit. We see that it is (0, 1.5)

Our equation would then be:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
