you have or
if you compare it to , you see that and which means you have a line that crosses {y-axis}}} at and has positive slope, so its graph goes through I and III quadrant and line is raising
since you already have one point to plot on a coordinate system, and it is (,), we need one more point to graph the line
let ...=>...; so, second point will be (,)
now we can graph it
