If the slope of the line passing through points M(2, 3) and N(x, 7) is 2, what is the value of x? A. -1 B. 1 C. 3 D. 5 相关知识点: 试题来源: 解析 D。本题创新点是通过斜率求坐标。斜率公式为 (y₂ - y₁)/(x₂ - x₁) ,即 (7 - 3)/(x - 2) = 2 ,...
Line C slants down from left to right. Line C has a negative slope. Using two of the points on the line, you can find the slope of the line by finding the rise and the run. The vertical change between two points is called the rise, and the horizontal change is called the run. ...
Slope, Numerical measure of a line’s inclination relative to the horizontal. In analytic geometry, the slope of any line, ray, or line segment is the ratio of the vertical to the horizontal distance between any two points on it (“slope equals rise over
The correct Answer is:If a=2 then b=0, and If a=−2 then b=4. Given, the slope of the curve 2y2=ax2+b at (1,−1) is −1. As, (1,−1) is on the given curve, then a+b=2… eq (1) Now, slope of the given curve at (1,−1) would be : dydx∣∣...
