The intercept of a straight line is divided into transverse intercept and longitudinal intercept. The transverse intercept is the abscissa of the intersection point between the line and X axis, and the longitudinal intercept is the ordinate of the intersection point between the line and the Y axis. If we want to get the transverse intercept, we only need to let y = 0, then we can find x, and we can get the longitudinal intercept so that x = 0. If y = X-1, the transverse intercept is 1 and the longitudinal intercept is -1.
Example:
Draw a straight line in a plane rectangular coordinate system.
4x+5y-20=0
Answer:
First calculate the intercept on the X and Y axes.
Let y = 0, then 4x-20 = 0, x = 5;
That is, the intercept on the x-axis is 5 and the intercept point is a (5,0).
Let x = 0, then 5y-20 = 0, y = 4;
That is, the intercept on the y-axis is 4 and the intercept point is B (0,4).
4X + 5Y = 9
Click "calculate" to output the result
X-axis intercept: 2.25
Y-axis intercept: 1.8
Result:
4X + 5Y = 9 X = 2.25; Y = 1.8
