If the slope of a straight line is Tana, then its inclination angle is a
The inclination angle must be between 0 ° and 180 ° and a may not be between 0 ° and 180 ° in the case of slope k = Tan a~
If the Tana of a straight line, then the inclination angle of the straight line is a
Is that right? Why?
If the Tana of a straight line, then the inclination angle of the straight line is a-_ -||If the slope of a straight line Tan a, then the inclination angle of the straight line is a
In the linear function y = KX + B, when K1 = K2, B1 is not equal to B2; K1 = K2, B1 = B2; K1 + K2 = 0, B1 = B2; K1 + K2 = 0, B1 + B2 = 0; K1 = K2, B1 + B2 = 0
What's the relationship between position and quantity? Urgent!
When K1 = K2, B1 is not equal to B2
Straight line parallel
