Answer:

[tex]\[y=\frac{1}{4}x-3\][/tex]

Step-by-step explanation:

Equation of a line which passes through two points (x1,y1) and (x2,y2) is given by:

[tex]\[\frac{y-y1}{y2-y1}=\frac{x-x1}{x2-x1}\][/tex]

(x1,y1) = (4,-2)

(x2,y2) = (-4,-4)

Substituting the values in the equation:

[tex]\[\frac{y-(-2)}{(-4)-(-2)}=\frac{x-4}{(-4)-4}\][/tex]

=> [tex]\[\frac{y+2}{-2}=\frac{x-4}{-8}\][/tex]

=> [tex]\[4y+8=x-4\][/tex]

=> [tex]\[4y=x-12\][/tex]

=> [tex]\[y=\frac{1}{4}x-3\][/tex]
