Question: how to find equation of line?
Answer: The slope-intercept formula of a line is written as y = mx+b, where m is the slope and b is the y-intercept (the point on the y-axis where the line crosses it). Plug the number you found for your slope in place of m. In our example, the formula would read y = 1x+b or y = x+b when you replace the slope value.
