(06.04 LC) Ashley was making a scatterplot using data that she collected about birds' heights (x) and their wingspans (y), both in inches. After plotting the points and her line of best fit, she found that the points (4,8) and (12,22) both fell right onto her line of best fit. Using this info, answer the questions below. The slope for her line of best fit will be [ Select ] . The y-intercept will be [ Select ] So her equation should be [ Select ] .
