What does slope represent?
In math, the slope of a line represents its steepness. It is the change in y values over the change in the values of x, or rise over run.
What does slope mean in math class?
slope is the steepness of a line, it is defined by the change in the y values divided by the change in the x values of any two points on a line (x1, y1) and (x2, y2) slope = (y1 - y2)/(x1 - x2)
What is the slope of x equals -7?
The slope is undefined. X = 7 (or any other number) gives you a vertical line. Since slope is defined as the change in y divided by the change in x, or rise over run, for a vertical line you end up dividing by 0, because there is no change in x. Thus, it is undefined.
Points 2 0 and 0 3 lie on line k. What is the slope of the line that is perpendicular to k?
Slope is defined as the change in x over the change in y. To find the change in x, subtract one of the x values from the other. To find y, subtract one of the y values from the other. It doesn't matter which order you do it in, but ALWAYS do it in the same order for both x and y.For the given points we get:(2-0)/(0-3)Which becomes:-2/3So the slope of our first line is -2/3. But we need to find the slope of the perpendicular line. To find the slope of a perpendicular line, we have to switch the numerator with the denominator (top number with the bottom number), then multiply by -1.Doing this gives us 3/2.
What do you know about the slope when x equals 0?
Without an equation, you know nothing about the slope of a line just because x equals 0. Slope is the change in y value divided by the change in x value over a segment of a line. When you only have a single x value, there is no change so the slope is undefined. Or if you are stating the value of x is 0 for all values of y, then the slope is infinite.
