The key features needed are the slopes and y-intercepts. If the slope and the y-intercept are the same then there are infinite amounts of intersections. If the slope is the same and the y-intercept is different then they will never intercept. Of the slope and the y-intercept are different, then they will intersect at one point.
Lines are the same if m1 = m2 and b1 = b2 (they intersect in infinitely many points) If b1 ≠ b2 and m1 = m2 then lines are parallel and do not intersect If m1≠ m2 then lines will intersect at one point
Because arithmetic sequences are sequences where the values have a constant change. But Geometric sequences are when the ratois of the values have constant change.
