X+3y= 6 find the slope m=3 I'm I correct

To calculate the slope, calculate the
rise (vertical) = 14588  8200 ft
run (horizontal) = 15842 ft
The slope is rise/run, convert to 100%.

Determine whether 7.5 is a soultion for the inequality.X>5. i chose yes I'm I correct

You're correct, but draw them on the number line to make sure you understand the answer.
∞+0+5+7.5+∞
Numbers on the right are greater than the numbers on the left. So if 7.5 is situated on the right of 5, then it is greater than 5.
