We first get the gradient of the equation of a line by taking the change in y over change in x

Hence our gradient will be

(6-9.5)/(8-1)=-3.5/7=0.5

Taking an arbitrary point(x,y) and using our gradient we get and one of the points above we get

(y-6)/(x-8)=0.5

y-6=0.5*(x-8)

y-6=0.5x-4

y=0.5x+2 or y=1/2x+2

which is the line of our equation the answer we are asked for.

A rocket travels 2.8x10^4 km h^-1. find how far it travels in 5 hours
mixas84 [53]

It is given in the question that, a rocket travels 2.8x10^4 km h^-1.

It means in one hour, the rocket travels

2.8* 10^4km.

And we have to find how much the rocket travels in 5 hours, and for that we have to do multiplication, that is

2.8*10^4 *5 = 14*10^4 = 1.4* 10^5 km
