Question

write an equation for the following graph.

Answer 1

Answer:

x+y+1=0

Side Explanation:

Use the intercept form equation since the x intercept and y intercept is clearly visible.

(Intercept form: $\frac{x}{a} + \frac{y}{b} = 1$   where a is x intercept and b is y intercept)

Here the x intercept is -1 and the y intercept is also -1.

Therefore the equation would be:

$\frac{x}{-1} + \frac{y}{-1} = 1$

i.e - x - y = 1

⇒ x + y + 1 = 0
