If you mean: x-intercept = -2/5 and y-intercept = 5, then we can solve this.
step 1 - notice that both of these are coordinates at (-2/5,0) and (0,5). We can find the slope of these as:
m+=+%28y2-y1%29%2F%28x2-x1%29
m+=+%285-0%29+%2F+%280-%28-2%2F5%29%29
m+=+5+%2F+%282%2F5%29+
m+=+25%2F2
--
The point-slope formula can be expressed as:
+y+-+y1+=+m%28x+-+x1%29
We use 1 point and our slope to create
+y+-+5+=+%2825%2F2%29%2A%28x+-+0%29
This becomes
y+=+%2825%2F2%29x+%2B+5
which is slope intercept form.
