Let y0=(2/5)x, y1=(2/5)x+3 and y2=(2/5)x-1
The graph of y0=(2/5)x is a straight line that passes thru the origin, O(0,0), of the coordinate plane, and goes upwards as x increases because the coefficient of x, the slope of line y0, is positive(=2/5). Slope is the ratio of coordinate changes, y to x or y/x, so this equation y0 indicates that y goes 2 units up as x goes 5 units right, positive.
y1=(2/5)x+3 is y0=(2/5)x shifted 3 units upwards, so line y1 intercepts y-axis at y=3. The slope of y1 is equal to that of y0(=2/5), so line y1 is parallel to line y0.
y2=(2/5)x-1 is y0=(2/5)x shifted 1 unit downwards, so line y2 intersepts y-axis at y=-1. The slope of y2 is equal to that of y0, so line y2 is parallel to line y0, and parallel to line y1 as well.
Therefore, choose the line that intercepts y-axis at y=-1, and parallel to line y= (2/5)x+3.
