Answer:

The line crosses the y-axis at -2

Step-by-step explanation:

y = mx + b 'm is the slope and b is the y-intersect (the place where the graph comes across the y-axis.

y = mx + b; y = mx + b; b = -2.

Answer:

(i)= 45 KPH, (ii) = 251 miles

Step-by-step explanation:

'Per' essentially means divide. Thus, to find Kilometres per hour, divide 270 by 6= 45. The bus is travelling at 45 KPH.

Then, to see how far a nine hour trip would cover, distance = speed * time = 251 miles.
