Question

BRAINLIEST !
The equation of a straight line is x + 2y + 6 = 0. write the equation in the form y = mx + c, state the gradient and y intercept.

Answer 1

Answer:

see explanation

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the gradient and c the y- intercept )

given

x + 2y + 6 = 0 ( subtract x + 6 from both sides )

2y = - x - 6 ( divide terms by 2 )

y = - $\frac{1}{2}$ x - 3 ← in slope- intercept form

with gradient m = - $\frac{1}{2}$ and y- intercept c = - 3
