Can someone show me how to do this? Write the slope-intercept (y = mx + b) form of the equation from the information given. Slope = -2 and the line goes through the point (-1,3)

OpenStudy (caozeyuan):

ok, so y=-2x+b, right?

OpenStudy (caozeyuan):

OpenStudy (abbycross167):

-1? @caozeyuan

OpenStudy (caozeyuan):

well, should be +1, right?
