Question 4/5 noints)

Answer 1

2x + y = -4

Explanation:

standard form of equation of straight line is

ax+by = c

that is terms containing x and y should be on LHS and constant term should be on RHS

______________________________________________

Given equation

y + 1 = - 2x - 3

lets bring -2x on LHS ,

add 2x on lHS and RHS

y + 1 + 2x = - 2x - 3 + 2x

=> y + 1 + 2x = -3

on lHS, 1 is there which constant term lets bring it on RHS

subtract 1 from both sides

y + 1 + 2x - 1= -3 -1

y + 2x = -4

rearranging it

2x + y = -4 (Answer)
