Question

Problem 3

Answer 1

Answer:

$-\frac{2}{5}$

Step-by-step explanation:

Given expression:

           2x + 5y = -10

The equation of a straight line is;

            y = mx + c

y and x are the coordinates

m is the slope

c is the intercept

 Now;

          let us write the given expression in slope intercept format;

            2x + 5y  = -10

                    5y = -2x - 10

                     y = $-\frac{2x}{5}$  - 2

So, the slope of the line is $-\frac{2}{5}$
