Step-by-step explanation:

t in 1200m:

$t = \frac{4500}{x} \\ x = 1200 \\ t = 4500 \div 1200 = 3.75$

t in 3750:

$t = \frac{4500}{x} \\ x = 3750 \\ t = 4000 \div 3750 = 0.12$

difference is:

3.75-0.12 = 3.63

Answer: $(y-1)=9(x-6)$

Step-by-step explanation:

If a line is passing through the point (a,b) and has a slope m, then the equation of the line in point-slope form is given by :-

$(y-b)=m(x-a)$

Given: A line that includes the point (6, 1) has a slope of 9.

The equation of line in point-slope form: $(y-1)=9(x-6)$

Hence, the required equation in point slope form: $(y-1)=9(x-6)$
