How to graph
5x+2y=-10


To be able to graph an equation, you need to know at least two points along the line. In order to find some points, you must first pick a number(prefferably low) for x, plug it into the equation, and solve. So, if I pick 1 for x:
5%281%29%2B2y=-10


Multiply:
5%2B2y=-10


Subtract 5 from both sides:
2y=-15


Divide both sides by 2:
y=-7.5


That gives you an ordered pair of (1,-7.5).


To check, plug these values into your equation:
5%281%29%2B2%28-7.5%29=-10


Multiply:
5-15=-10


Subtract:
-10=-10


To find another point, simply repeat this process. Plot both points on your graph, and then you can draw your line.
