To find x-intercept, put y = 0 in the equation and find x.
OpenStudy (aum):
8x - 1/3 * y = 16
To find x-intercept, put y = 0:
8x - 0 = 16
x = 16/8 = 2
x-intercept (2, 0)

:D what about the first question?
OpenStudy (aum):
For the first one imagine joining the points A and C with a straight line.
This line will go through the left top corner of each small square in the grid.
Where does it cross the y-axis?
OpenStudy (anonymous):
The left i think

What are the coordinates of the point where it crosses the y-axis?
The x-coordinate is obviously 0. What is the y-coordinate?
OpenStudy (anonymous):
(0, -1?)
OpenStudy (aum):
Yes!

Thanks so much again :D
