To find the equation you would first need to find the slope. if you use the formula y2 - y1/x2 - x1 = 5-6/2+4 (plus four because minus a negative turns into positive). your slope (m) would be -1/6. Since you have a point and a slope you can you point slope form ( y-y1=m(x-x1) ) to find the equation. Using the first coordinate (-4,6) and the slope (-1/6) your point slope form would be y-6=-1/6(x+4). Now you simplify your equation down. Multiply the -1/6 into the parentheses, y-6=-1/6x - 2/3. After that just add the 6 to the -2/3 to get y by itself, y= -1/6x + 16/3. Therefore y=-1/6x + 16/3 would be your equation
L=25 If the length is 25 yards then you use 50 yards of fencing for the length, this leaves ten yards for each width of fencing each. 10 yards is 15 yards less than 25 yards showing that this is the correct answer.
