Explanation:

Answer:

\large{\underline{\underline{{\sf{\purple{Given \:Equations:-}}}}}}

GivenEquations:−

➨ 2x + 3y = -5

➨ x + y = -1

━━━━━━━━━━━━━━━━━━━━━

Putting the value of x = 0 in equation 2x + 3y = -5 :-

➨ 2(0) + 3y + 5 = 0

➨ y = \dfrac{-5}{3}

Putting value of y = 0 in equation 2x + 3y = -5 :-

➨ 2x + 3(0) + 5 = 0

➨ x = \dfrac{-5}{2}

━━━━━━━━━━━━━━━━━━━━━

Putting the value of x = 0 in equation x + y = -1 :-

➨ 0 + y + 1 = 0

➨ y = -1

⚘ Their Coordinates are ( 0 , -1 )

━━━━━━━━━━

Putting the value of y = 0 in equation x + y = -1 :-

➨ x + 0 + 1 = 0

➨ x = -1

⚘ Their Coordinates are ( -1 , 0 )

Both lines intersect at a point (2 , -3).
