Given the slope and a point on the line, use the point-slope formula for the equation of a straight line.
y-6 = (-5/9)(x-9)
This can be put into other forms. For example,
Multiplying all terms by 9 results in 9y - 54 = -5(x-9) = -5x + 45
Solving for y: 9y - 54 = -5x + 45
+54 = +54
---------------------------
9y = -5x + 99
Then y = (-5/9)x + 11.

Answer:
58.6% of the variation in length (in cm) of new born boys and their weight (in kg) is explained by the line of best fit.
Step-by-step explanation:
Given the following :
R² value = 58.6% comparing the length (cm) of new born boys to their weight (kg)
The R² value is called the Coefficient of determination. It is obtained by taking the square of the correlation Coefficient (R). The value gives the proportion of Variation between the independent and dependent variables which is explained by regression line. In the scenario above, the R² value means that 58.6% of the variation in length in centimeter of new born boys and their weight (in kg) is explained by the line of best fit. While (100% - 58.6% = 41.4%) is due to other factors.
An expression for “7 divided by c” is 7/c or 7 ÷ c
