Find slope for 2x+5y=8?

Nitella [24]

First thing, you need to transform this equation to the form of y = ax + b

So you get:
2x + 5y = 8
5y = -2x + 8
$y = -\frac{2}{5} x + \frac{8}{5}$

In the form of y = ax + b, a is the slope.
In $y = -\frac{2}{5} x + \frac{8}{5}$ , you can see " $- \frac{2}{5} x$ ", and always the number before x is the slope
So, the slope of 2x + 5y = 8 is $- \frac{2}{5}$

Hope this Helps :)
