Finding y intercept and x intercept is easy:
X intercept will be of the form (x,0) and y intercept will be of the form (0,y)
● If you put x=0 in the equation, you will get y-intercept.
● If you put y=0 in the equation, you will get x-intercept.

Given equation: 2x - 4y = 10
◆ Put x = 0
2×0 - 4y = 10
=> -4y = 10
=> y = 10/(-4)
=> y = -5/2
Thus y intercept is (0, -5/2)
◆Put y = 0
2x - 4×0 = 10
=> 2x = 10
=> x = 10/2
=> x = 5
Thus the x intercept is (5,0)
Markup=10.82(72/100)≈$7.79 (to nearest cent)
retail=10.82(100+72)/100≈$18.61 (to nearest cent)
3x-x+2=4, That should be your answer if that is what your looking for
Since, the co-interior angles(55° and 125°) are supplementary(sum is 180), therefore the lines are parallel.
