Determine the slope and y-intercept of the graph: 3x + y = 8.

put the problem in slope intercept form (y = mx + b) with m being the slope and b being the y intercept.

3x + y = 8

y = -3x + 8

y = mx + b

so m = ?

and b = ? - June 23rd 2005, 03:04 PMHayabusa
My answer is 8. Am I correct?

yes for the y-intercept, what about the slope?

- June 23rd 2005, 03:33 PMHayabusa
The slope is 0.

Thank you for the help. - June 23rd 2005, 03:40 PMalmostdone
Actually rhe slope is -3.

y = mx + b

where m is the slope and b is the y intercept.

so,

y = (-3)x + 8

y = (m )x + b
