9x9=81
so there is 9 on 2 sides, which is 18 when it gets added together. DONT FORGET ABOUT THE OTHER 2 SIDES!! you have four sides of the square so 9x4=36. I believe the answer is actually 36

Line L passes through the points (0, --3) and (6,9). (a) Find the equation of line L.

valentina_108 [34]

Step-by-step explanation:

Given points are :

$(0,\:-3)=(x_1,\:y_1) \:\&\: (6,\:9)=(x_2 ,\:y_2)$

Equation of line in two point form is given as:

$\frac{y -y_1 }{y_1 -y_2 } = \frac{x -x_1 }{x_1 -x_2 } \\ \\ \therefore \frac{y -( - 3)}{ -3 -9 } = \frac{x -0 }{0 -6 } \\ \\ \therefore \frac{y + 3}{ -12} = \frac{x }{ -6 } \\ \\ \therefore \frac{y + 3}{ 2} = \frac{x }{1} \\ \\ \therefore \: y + 3 = 2x \\ \\ \huge \red{ \boxed{\therefore \: 2x - y - 3 = 0}} \\ is \: the \: required \: equation \: of \: line.$

Step-by-step explanation:

Step 1: Define

y = home runs

x = hits

[Best Line of Fit] y = 0.15x - 1.5

We can use this to predict the average of the scatter plot.

home runs = y = 35

Step 2: Solve for x hits

Substitute [BLF]: 35 = 0.15x - 1.5
Add 1.5 on both sides: 36.5 = 0.15x
Divide 0.15 on both sides: 243.333 = x
Rewrite: x = 243.333

Remember that this is a prediction. According to the best line of fit, we would need approximately ~243 to get 35 home runs.
