Put the equation in standard form with a positive x coefficient. y + 3 = -5(x+1)

5x + y = - 8

Step-by-step explanation:

The equation of a line in standard form is

Ax + By = C ( A is a positive integer and B, C are integers )

given

y + 3 = - 5(x + 1) ← distribute

y + 3 = - 5x - 5 ( add 5x to both sides )

5x + y + 3 = - 5 ( subtract 3 from both sides )

5x + y = - 8 ← in standard form

x² + 11x + 18 < 0  

[-11 ± sqrt(121 - 72)]/2 = (-11 ± 7)/2  

solution: (-9, -2)
