HEWP Harry, Ron & Hermione are traveling to Hogwarts via the Hogwarts Express. Hogwarts is approximately 600 miles from Central London. If the Hogwarts Express travels at approximately 65mph, in how many hours will their train be 15 miles away from their destination?

you have to find the same variables -3n - 5n so this would be -3n +(-5n) which equals -9n

d

step-by-step explanation:

the two points from this line are   (0,4)   & (2,-2)

we can call

now, lets find the slope (m):

now finding b (the y intercept). this is the point at the y-axis where the line cuts the axis. looking at the graph, it is y = 4. so the point is 4. hence b = 4

the slope-intercept form is given by  

putting the points, we have:

d is the correct answer.
