In this question, the bus had traveled 4 parts of the distance which equal to 12 miles. If you put it into an equation it will become
4 parts = 12 miles
1 parts = 12miles/4= 3 miles
The total distance of town A to town B is 8 parts. So, the total distance in miles would be:
8 parts * 3miles/part= 24 miles
The correct answer is C) 1/3 and (0, 1)
The y-intercept part is somewhat simple. In order for it to be a y-intercept, the x value of the ordered pair must be 0. That is only true in B and C, therefore they are the only possible answers.
To find the slope, we must choose two points on the line and use the slope formula. We can start by using the y-intercept (0, 1) and also (3, 2). Now we use the slope formula.
m = (y2 - y1)/(x2 - x1)
In this equation m is equal to slope, the first point is (x1, y1) and the second point is (x2, y2)
m = (y2 - y1)/(x2 - x1)
m = (2 - 1)/(3 - 0)
m = 1/3
Now knowing the slope, you can match this with answer C.
The answer would be four and 2 thousandths
