There are 600 tenths of a second in one minute.
3/4 of a kilometer is 0.75 kilometer.
600 x 0.75 = 450
The correct answer is 5. This is because rate of change of a function or a line is its gradient. As we can see that the line is horizontal then the gradient must be equal to zero too.
On the other hand the equation is written in the form of y = mx + c where m is the gradient or slope and c is the y intercept so the gradient is equal to 5 if we match the places. So it is 5 times greater.
Answer:

Step-by-step explanation:
Given line ;

1. Perpendicular and passes through (4,-6)

Substitute the values above into slope intercept form ; y=mx+b and solve for b.

Substitute new values into ; y =mx+b.

2.Parallel and passes through (4,-6)

Substitute values into point slope form and simplify

Answer:
we need a figure
