Respuesta :

so you have yo turn it into the correct form first so you add 4x to both sides and come out with 2y=4x-12 them you divide each side by 2 because you have to have to by itself and you come out with y=2x-6 so the slope is 2x and the y intercept is -6
solve for y basicaly
2y-4x=-12
divde both sides by 2
y-2x=-6
add 2x to both sides
y=2x-6
