To write a fraction as a decimal, divide the numerator (top) of the fraction by the denominator (bottom) of the fraction. Use long division, if necessary, and note where to place the decimal point in your answer. For example, to write as a decimal, divide 3 by 5, which will result in 0.6.
well if you can find the slope then choose one of your ordered pair and plug them in tot he corresponding variable. since you don't know what the y intercept you basically find x which will be the y int.
