1 yard=3 feet so 100 yard=300 feet
Start with 2. Then subtract from it (2x - 7)^2.
2 - (2x - 7)^2
Yes it would be 59. 59 is the correct answer. Hopefully
Substitute x=0 in the equation and find the value for y that makes the resulting equation true. For example, in the equation x-2y=2, when x=0, the equation becomes -2y=2. Since y=-1 makes this equation true, one point on the line is (0,-1)
