The equation of line L is obtained according to the following conditions: (1) the intercept on the x-axis is - 2, and the intercept on the y-axis is - 3 The equation of the line L is obtained according to the following conditions, (1) The intercept is - 2 on the x-axis and - 3 on the y-axis (2) It passes through point a (- 5,0) with equal transverse and longitudinal intercept
The equation of the line L is obtained according to the following conditions,
(1) The intercept is - 2 on the x-axis and - 3 on the y-axis
That is: X / (- 2) + Y / (- 3) = 1
That is: 3x + 2x + 6 = 0
(2) It passes through point a (- 5,0) with equal transverse and longitudinal intercept
Obviously, the intercept is not equal to 0
Let X / A + Y / a = 1
-5/a+0=1
a=-5
That is, the equation x / (- 5) + Y / (- 5) = 0
That is, x + y + 5 = 0
If the intercept of a line ax-6y-12a = 0 (a ≠ 0) on the x-axis is three times of its intercept on the y-axis, then a is equal to 0______ ．
It can be seen from the meaning of the question: the linear equation can be reduced to X12 + y − 2A = 1, and the intercept of the line on the x-axis is three times of its intercept on the y-axis, so 12 = 3 (- 2A), the solution is a = - 2, so the answer is: - 2
What is the intercept of line 6x + Y-12 = 0 on the x-axis? What is the intercept on the y-axis?
Quick solution
6x+y-12=0
(1) When y = 0; X = 2
The intercept on the x-axis is 2
(2) When x = 0; y = 12
The intercept on the y-axis is 12
