Gradient #=2#, Intercept#=-4#

Explanation:

We can rearrange this to be:

#y+4=2x#

#rArr y=2x-4#

#therefore# The gradient is #2#

#therefore# The intercept is #-4#

Slope: #2#, Y-intercept: #-4#

Explanation:

For the y-interception just check what #y# is when #x=0#.
This can be done by rearanging the equation by first adding #y# to both sides, then subtracting with #4#.

This will result in: #y=2x-4#.

When #x=0#, #y=-4#.

The slope is basicly the constant infront of the #x# (when simplified to the #y=ax+b#).

So the slope is #2#.
