Since x = -2/5 is a vertical line which crosses the x axis at -2/5, its slope is undefined and it has no y intercept.

To find the slope and -intercept of an equation, put it in the y=mx+b form, m will be the slope, and b will be the y value of teh y-intercept.
since there is no y, this is a vertical line, parallel to the y axis, and 2/5 unit to the left of the axis. There is no y-intercept, and the slope is undefined.

slope = 1 and y intercept = 2/5

There is no slope. There is no y-intercept. It's a vertical line that crosses point (-2/5) on the coordinate plane.
It could be, you didn't give us enough information...

Slope = undefined (can't divide by 0)
y-intercept: there is none

the line x= -2/5 is vertical and cuts the x-axis at -2/5
this line will never cut the y-axis therefore there is no y intercept
if you have two points on the line A(x1,y1) and B(x2,y2)
the gradient(slope) of the line is (y2-y1)/(x2-x1)
but since x2=x1, (x2-x1)=0 and the slope is a singularity- ie it is
undefined
i hope that helps

I dont know. I forgot since high school. Dont need to know for my audio production major. The only thing i want to say is if someone does know, please do more than give her the answer. tell her how u got it also...that could come in handy
