A graph shows the relationship between two or more variables
To graph an equation with slope of -2/5 plot (2, -4) on the plane and then move;
2 steps down and 5 steps right to plot the next point at (7, -6)
Reason:
To graph an equation with a slope -2/5 that passes through the point (2, -4), the steps are;
Plot the point (2, -4) on the graph
Move two steps down vertically to the point (2, -4 - 2) = (2, -6)
Then move five steps to the right to point (2 + 5, -6) = (7, -6)
The point (7, -6) is another point on the graph
Join the two points (2, -6), and (7, -6), with a straight line and extend it to complete the graph
Therefore;
To graph an equation with slope of -2/5 plot (2, -4) on the plane and then move 2 steps down and 5 steps right to plot the next point at (7, -6)
