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.
