You would first convert meters to centimeters which would equal 650cm. so then you take 129 and multiply it by 4 because that is how many days it will be growing. you take the product of 129 and 4 (which is 516) and add it to the 650 that you started with on monday morning. your answer will be
since the line is parallel it has the same slope so we have y = 3x + b. plug in the point (2,10) to get 10 = 3*2 + b, so b=4. so the equation is y = 3x +4
