Hope this helps!
It must be true that one of the numbers is negative. Hope that helps!!
Solve the equation to get values for x and y.
For example,
When x is 0,
y = 1
You have one point on the line (0,1)
Now, when y = 0,
x = 36/5 = 7.2
You have one more point on the line (7.2,0)
Plot these points on the x and y axes.
Draw a straight line joining these two points. ( I hope you can plot the points)
