Whích equation represents a line which is parallel to the line7x + 5y = -20?

Sagot :

We can rewrite the equation for this line as follows:

7x + 5y = -20

5y = -7x - 20

y = (-7/5)x - 4

Now, let's look at the general equation of a line:

y = ax + b.

In this equation, a is the slope of the line.

All parallel lines to this one will have the same slope. So, we need to identify the slope of the given equation. And that is:

a = -7/5 = -1.4

Therefore, all equations in the form y = -1.4x + c, where c is a constant, represent lines parallel to the given one.
