4x 3y 12 What is the xintercept and yintercept of this lin
4x + 3y = 12
What is the x-intercept and y-intercept of this line?
Solution
Y intercept for a function is value of y when x is equated to zero.
So subtitute x = 0 in 4x + 3y = 12
=>4(0) + 3y = 12
=> y = 12/3
=> y = 4
So this function bears a value y = 4 when x = 0
therefore the y intercept for \'4x + 3y = 12\' is 4.
Similarly, x intercept for a function is the value of x for which y = 0
So substitute y = 0 in 4x + 3y = 12
4x + 3(0) = 12
=> 4x = 12
=> x =12/4
=> x = 3
So the x intercept for this function is 3.
