Question

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

Answer 1

Answer:

$(-3, \frac{9}{5})$

Step-by-step 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.

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

$-6 + 5y = 3\\\\5y = 9\\\\y = \frac{9}{5}$.

Then the ordered pair is:

$(-3, \frac{9}{5})$
