It is rational and equal to 0. square root of 28 simplifies to 2 root 7, because you can take out the 4 and leave the 7 under the radical. because sq rt of 28 is 2 root 7, it's the same as the first term so it equals 0
The slope of the current line is -2/7. To find the slope of the line perpendicular to it, find the negative reciprocal of the slope. So it would be 7/2. The y intercept or the b would remain the same so the equation would be y=7/2x+8. Hope this helps.
