The y-intercept of a line is where the line goes across the y line.
Does that answer your question?
Perimeter of rectangle is 2L + 2W
perimeter is 296
length of field is 79
Solve
2L + 2W = 296
2(79) + 2W = 296
158 + 2W = 296
2W = 296 - 158 = 138
W = 138/2 = 69 yards
12x-30 would be the accurate answer
If 19 is half (50%) of something, find that number you would just have to multiply 19 by 2.
This means that 19 is 50% of 38.
