PLZ HELP ASAP!!!! A line has a slope of -1/2 and a y-intercept of 3. Which equations represent the line? Choose all answers that are correct. A. 2y=6 x B. x 2y=6 C. y=-1/2x 3 D. (y-2)=-1/2(x-2)

Answers

slope intercept form is y=mx+b
so y=-1/2x+3 would be correct
B (assuming it's x+2y=6?) and D would also be correct, because you'll get y=-1/2x+3 if you arrange them in the y=mx+c form.
