Yes, you can definitely write decimals in slope-intercept form for b. The slope-intercept form of a linear equation is represented as y = mx + b, where m is the slope and b is the y-intercept.
If your y-intercept b is a decimal, you simply write it just like any other number. For example, if the y-intercept is 2.5, the equation would be y = mx + 2.5. The use of decimals doesn’t change the format of the equation; you can use any number, whether it’s whole or a fraction or decimal, as the y-intercept.
This means that whether b is 0.5, 3.75, or -1.2, all are valid values for the y-intercept in the slope-intercept form. Just ensure that when you’re dealing with calculations involving these decimals, you maintain proper precision to arrive at the correct results.
