Slope and y-intercept formula is y=mx+b, where b = y-intercept and m = the slope of the line. So, in the problem for cx + y = d, c is a substitute for m and d is a substitute for b.
Solving for y-intercept .. the answer is d.
Solving for the slope .. y = -cx +d or -c.
In general the slope and intercept of `y=mx+b` is
m is the slope and b is the y-intercept.
`cx+y=d` can be re written as
`cx+y = d`
The above equation the slope is `m= (-c) and b= (d)` is y intercept
