standard form of slope of -2 and y-intercept equal to 6

OpenStudy (anonymous):

standard form ?

OpenStudy (mokeira):

equation is y=mx+c you have m=-2 and you have c=6 can you substitute in that equation

OpenStudy (mokeira):

then tell me what you get

OpenStudy (anonymous):

y=2x+6

OpenStudy (mokeira):

m is -2, not 2

OpenStudy (anonymous):

but im finding a standard form ??? Ax + By = C ??? they are the same ?

OpenStudy (mokeira):

i never thought you change the sign....

OpenStudy (mokeira):

when you say standard form...are you refering to equation of a line?

OpenStudy (anonymous):

y=-2x+6 ryt ?

OpenStudy (mokeira):

exactly

OpenStudy (anonymous):

how about (0,-7) with A slope of 5 ?

OpenStudy (mokeira):

in those case, you use the formula \[m=\frac{ \Delta y }{ \Delta x }\] do you know it?
