Answer:
The x-intercept is : (22, 0)
Explanation:
Given the table
x y
48 30
61 45
74 60
From the table, it is clear that every y value is changing 15 units, and every x is changing 13 units. Hence, it is a straight line.
Hence, we can find the other values of this straight line as well.
so
When the value of y = 15 i.e. (30-15), then the value of x will
be 35 i.e. (48 - 13).
as
y = 30 - 15 = 15, and x = 48 - 13 = 35.
Similarly,
When the value of y = 0 i.e. (15-15), then the value of x will be 22 i.e. (35-13).
as
y = 15-15 = 0, and x = 35 - 13 = 22.
As we know that the x-intercept is the point where the line crosses the x-axis. At this point y = 0.
so, as we have checked that when the value of y = 0, then the value of x = 22.
Therefore, the x-intercept is : (22, 0)
