Y= 2x+6 You just have to go back wards from what you have. You already know the slope is 2 and slope is the change is y over the change in x. 2=2/1 So every time you take away 1 from x, you’re going to take away 2 from y. (2,10) will become (1,8) which will be come (0,6). You know have your y intercept (6) So the equation for the line is y=2x+6
To find the answer you will have to multiply 800 by 10. 800 multiplied by 10 equals 8,000 The final answer is : The skyway express train travels about 8,000 miles in 10 days
