Answer:

The equation of the parallel line will be y = -2.5x - 8.

Explanation:

First things first, let's rearrange the line equation provided into a more standard form:


5x + 2y = 14


5x - 14 = -2y


(5x - 14)/(-2) = y


y = -2.5x + 7

Therefore, we can see that this line has a slope (the coefficient preceding x) of -2.5. The parallel line must therefore also have a slope of -2.5.

Now, let us set the y-intercept of the parallel line to be (0, a) (since it must be on the y-axis).

If we factor in all of this, we get the equation:


(a-(-3))/(0-(-2)) = -2.5

Remember, the slope is found by dividing the vertical difference with the horizontal difference.


a - (-3) = -2.5(0+2)


a + 3 = -5


a = -8

Hence, the equation of the parallel line will be y = -2.5x - 8.

Hope this helped!
