To round a number to the nearest tenth, you need to look at the digit in the hundredths place, which is the second digit after the decimal point. In this case, we are given the points A(1,4) and (6,8), which are coordinates on a graph. However, rounding to the nearest tenth doesn't apply in this context because we are dealing with whole numbers rather than decimal numbers or fractions. Rounding to the nearest tenth is typically done for numbers that have decimal places.
