Hey there! I'll assume we're using the slope-intercept form equation: y = mx + b m = slope b = y-intercept First, we keep the y, because it's value depends on the x value given. Next, we find the slope. Slope is defined as rise/run, so we take two points on the graph, find how much taller one is from another, and how far right/left they are, put those values over each other, and we have out slope (m). Finally, we need to determine the y-intercept, and that's as simple as seeing where the line crosses the y axis and writing down that value. Hope this helps!
