5/0=undefined

**math**

Remember m is the slope and b is the y-intercept So first isolate y, 5x-2y=-1 -2y=-5x-1 y=5/2x+1/2 Therefore, the slope is 5/2

**math**

yeah, true. For x intercept, sub y=0 into the equation, and you'll get 13/8 For y intercept, sub x=0 into the equation and you'lll get 13/3
