The condition for the parallelism of straight lines on the graph is the equality of the slopes of the straight lines. That is, if there are two straight lines y1 = a1x + b1 and y2 = a2x + b2, then they will be parallel if a1 = a2. In our case, the slope k should be equal to the slope of the second straight line – 7.
