Q. The scatterplot and line of best-fit show puppies' weights over time.Which equation best represents the line of best fit?y=1.8x+1.1y=1.2x+0.9y=0.9x+1.2y=1.1x+1.8
Analyze Scatterplot Trend: Analyze the scatterplot to determine the general trend of the data points. Assuming the scatterplot shows a positive linear trend, we need to find the line of best fit that closely matches this trend.
Compare Equation Slopes: Compare the slope of each given equation to the trend observed in the scatterplot. If the scatterplot shows a steep positive slope, equations with higher slope values are more likely candidates.
Calculate Approximate Slope: Calculate the approximate slope from the scatterplot.Assuming the scatterplot data points range from (0,1) to (10,20), the slope m can be calculated as:m=10−020−1=1019=1.9
