How to find the x and y-intercepts of a function?
Answer: To find the x-intercept of a line, we substitute y = 0 in the equation and find the corresponding value of x, and to find the y-intercept of a line, we substitute x = 0 in the equation and find the corresponding value of y.
Let's understand the problem with the help of an example.
Let's find the x and y intercepts of 2x + 4y = 8.
To find the x-intercept, put y = 0.
Hence, 2x + 4(0) = 8; we get x = 4.
Therefore, the x-intercept of the line represented by 2x + 4y = 8 is 4.
To find the y-intercept, put x = 0.
Hence, 2(0) + 4y = 8; we get y = 2.
Therefore, the y-intercept of the line represented by 2x + 4y = 8 is 2.
The x and y-intercepts of the line are given in the image above.
