Answer:

The equation of the parallel line would be y = -2/5x - 2

Explanation:

In order to find this, we first need to find the slope of the first line. We can do this by solving for y.

2x + 5y = 10

5y = -2x + 10

y = -2/5x + 2

Now we know the slope to be -2/5 since parallel lines have the same slope. So we can use point-slope form to find the equation of the line.

y - y1 = m(x - x1)

y - -4 = -2/5(x - 5)

y + 4 = -2/5x + 2

y = -2/5x - 2
