If you plot the points (7, 4) and (6, 3), you can gather information about the slope of the line. From point (7, 4) you would go down two, and go to the left two to get (6, 3).
For the next point, you would do the same. From point (6, 3) you would go down two, and go the left two. You would then get (5, 2).
Because it asks for the x-intercept, you would use the slope to plot points on the line until you reach the x-axis.
The points on the line would then include:
(3, 0) is the point at which the x-intercept lies. Therefore, your answer is (3, 0).
Thank you so much! I see what I did wrong. I got the 37.5 part, but after that, I was beyond confused! I understand a lot better:)
So, would that mean the ship was 31 miles to the south and 21 miles to the west of where the ship left port?
I graphed the point, and that's what my conclusion was, I just want to be sure!
Thank you again xx
