How do i find the slope of a line parallel to y=3x+8

Don't know how to find x given these segment lengths

Can someone check if i did this right since i really want to make sure it’s correct. if you do you so much

72 the length of a side of a triangle is 36. a line parallel to that side divides the triangle into two parts of equal area. find the length of the segment determined by the points of intersection between the line and the other two sides of the triangle.
