Card 1 of 24
What does a positive gradient show about a line?
A
It rises from left to right.
B
For two points (x1,y1)(x_1,y_1)(x1,y1) and (x2,y2)(x_2,y_2)(x2,y2), the gradient is m=y2−y1x2−x1\boxed{m=\frac{y_2-y_1}{x_2-x_1}}m=x2−x1y2−y1.
C
The output change per one-unit input increase.
D
Its gradient is undefined, and yyy is not single-valued.
