The x-intercept of a line is the value of x when the line crosses the x-axis. This happens when y = 0. Thus, the x-intercept can be found by making y = 0 in the given equation:
2x + 4y = 12.4, y = 0
2x = 12.4
x = 12.4/2
x = 6.2
The y-intercept, similarly, is the value of y when the line crosses the y-axis. This happens when x = 0. Thus, the y-intercept is given by:
2x + 4y = 12.4, x = 0
4y = 12.4
y = 12.4/4
y = 3.1
Therefore, the answer is:
x-intercept = 6.2
y-intercept = 3.1
