The slope of the line is 9/4 for parallel lines like this. y = mx + b is the general equation y = 9/4 x + b is what you have so far 3 = 9/4 *25 + b You need to solve for b. 3 = 56.25 + b - 53.25 = b
y = 9/4 x - 53.25 I don't know which part to round. I suppose both y = 2x - 53 is one possibility If it is one of them then
