-10x-5y%2B20=0 Start with the given equation



-5y%2B20=0%2B10xAdd 10x to both sides


-5y=0%2B10x-20Subtract 20 from both sides


-5y=10x-20 Combine like terms on the right side


y=%2810x-20%29%2F%28-5%29 Divide both sides by -5 to isolate y



y=%2810x%29%2F%28-5%29-%2820%29%2F%28-5%29 Break up the fraction



y=-2x%2B4 Reduce


So the equation is in slope-intercept form y=mx+b where m=-2 and b=4
