Complete the equation for the standard form of the line that has an x-intercept of -5 and a y-intercept of -4.
Verdich [7]

Answer:

Intercept form     \frac{x}{-5} + \frac{y}{-4} = 1

The standard form of the equation of the line

   4 x + 5 y +20 =0

Step-by-step explanation:

<u><em>Explanation</em></u>

Given that x-intercept (a) = -5

and y-intercept (b) = -4

Intercept form

                 \frac{x}{a} + \frac{y}{b} = 1

                \frac{x}{-5} + \frac{y}{-4} = 1

          ⇒   \frac{4x+5y}{-20}  = 1

                4 x + 5 y = -20

<u><em>Final answer:-</em></u>

The standard form of the equation of the line

               4 x + 5 y +20 =0
