I NEED help

johnweldon1993 · Answer

each equation is in slope intercept form...

y = mx + b

"m" is your slope
"b" is your y-intercept

So which is your answer?

anonymous · Answer

i got A because i did Y=-2x+4 and i got 2 for my answer

johnweldon1993 · Answer

You should have gotten B ...there is nothing to do to the equation other than look at it and see what takes the place of 'm' and what takes the place of 'b'

so y = mx + b

Answer choice B is

    y = -2x + 4

Compare them...it looks like m = -2 and b = 4  ...showing that B is the correct answer

ooooo ok i see i was confused about this lesson so now i understand it, you don't try to solve it ok know i understand you just put the mx and b in their places got it 
thank you sooooo much
