Question

Para la ecuación 2x+5y-3=0, halla la coordenada que falta (-3,?)

Answer 1

`(-3, (9)/(5))`

Explanation:

We have the equation
`2x + 5y-3 = 0`.

The ordered pairs of this equation have the form
`(x_0, y_0)`

Where x is the independent variable and y is the dependent variabe.

That is, the points belonging to the line
`2x + 5y-3 = 0` have the form
`(x_0, f (x_0))`

For
`y = f(x)`.

So, we need to find
`f(x_0)` for x_0 = -3.

Then we substitute x = -3 into the equation and clear the value of y.

`2(-3) + 5y -3 = 0`

`-6 + 5y = 3\\\\5y = 9\\\\y = (9)/(5)`.

Then the ordered pair is:

`(-3, (9)/(5))`
