Question

Shown to the right is a scatter plot that indicates a relationship between the percentage of adult females in a country who are literate and the mortality of children under five (per thousand). Also shown is a line that passes through or near the points. Find a linear function that models the data by finding the slope-intercept form of the line's equation. Use the function to make a prediction about child mortality based on the percentage of adult females in a country who are literate. Using the indicated points on the graph of the line, find the slope-intercept form of the line's equation. Use the percentage of adult females who are literate as x-value. f(x) = (Use integers or decimals for any numbers in the equation)

Explanation / Answer

At x = 0, y = 234

So, y intercept is 234

Also, this line passes through (60,156),

156 = 60m+234

m = -1.3

So, equation is

f(x) = -1.3x+234
