Solved by pluggable solver: Converting Linear Equations in Standard form to Slope-Intercept Form (and vice versa)
Convert from standard form (Ax+By = C) to slope-intercept form (y = mx+b)


2x%2B5y=-10 Start with the given equation


2x%2B5y-2x=-10-2x Subtract 2x from both sides


5y=-2x-10 Simplify


%285y%29%2F%285%29=%28-2x-10%29%2F%285%29 Divide both sides by 5 to isolate y


y+=+%28-2x%29%2F%285%29%2B%28-10%29%2F%285%29 Break up the fraction on the right hand side


y+=+%28-2%2F5%29x-2 Reduce and simplify


The original equation 2x%2B5y=-10 (standard form) is equivalent to y+=+%28-2%2F5%29x-2 (slope-intercept form)


The equation y+=+%28-2%2F5%29x-2 is in the form y=mx%2Bb where m=-2%2F5 is the slope and b=-2 is the y intercept.

find the slope of the graph of the equation
2x+5y=-10
---------------
Put the equation in slope-intercept form (y=mx+b) where m is the slope.
5y=-2x-10
y = (-2/5)x - 2
slope = 2/5
