A line passes through the points (7,4) and (6,3). What is the x-intercept?
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:
(7, 4)
(6, 3)
(5, 2)
(4, 1)
(3, 0)
(3, 0) is the point at which the x-intercept lies. Therefore, your answer is (3, 0).
