Question

How do I find the slope in this equation -2x - 4y = 10

Answer 1

In y = mx + b form, the slope is in the m position.
So lets put your equation in y = mx + b form...
-2x - 4y = 10 --- add 2x to both sides
-4y = 2x + 10 --- divide both sides by -4
y = 2/-4x + 10/-4
y = -1/2x - 5/2
Now what number is in the m position ? That number is your slope.
