What is the slope and y intercept for y equals 9?
y = 9 is a horizontal line with slope 0. Slope = (y2 - y1)/(x2-x1), and y is constant so that numerator is always 0. The y-intercept is where the line crosses the y-axis when x=0. Since y is always 9 in this case, that is the y-intercept.
What if the numerator is 0?
If the numerator is 0, the fraction equals 0, because there is no part of the whole.
What kind of slopes do perpendicular slopes have?
Negative reciprocals. That is, if one line has slope m (m ≠0), then the perpendicular to it has slope -1/m. If m = 0, the slope of the perpendicular is not defined - the line is of the form x = k.
What is the cosine of a ratio that has 0 as its numerator?
If the numerator is 0 AND the denominator is not 0, then the ratio is 0. And cosine of 0 is 1.
If the slope of a given line is 0 what is the slope of an orthogonal line?
If the original slope is 0, then the opposite reciprocal of 0 is still 0. Oops! Reciprocal of 0 (n/0) is undefined! A vertical line has undefined slope, the horizontal line has slope of 0.
What is a slope of 0?
A horizontal line has a slope of 0. If you're using the slope formula, then when the numerator is equal to 0 then the slope is 0.
What is the slope and y intercept for y equals 9?
y = 9 is a horizontal line with slope 0. Slope = (y2 - y1)/(x2-x1), and y is constant so that numerator is always 0. The y-intercept is where the line crosses the y-axis when x=0. Since y is always 9 in this case, that is the y-intercept.
What is a fraction with a numerator of 0 called?
If the numerator is 0, the fraction equals 0.
What if the numerator is 0?
If the numerator is 0, the fraction equals 0, because there is no part of the whole.
What is the cosine of a ratio that has 0 as its numerator?
If the numerator is 0 AND the denominator is not 0, then the ratio is 0. And cosine of 0 is 1.
What kind of slopes do perpendicular slopes have?
Negative reciprocals. That is, if one line has slope m (m ≠0), then the perpendicular to it has slope -1/m. If m = 0, the slope of the perpendicular is not defined - the line is of the form x = k.
If the slope of a given line is 0 what is the slope of an orthogonal line?
If the original slope is 0, then the opposite reciprocal of 0 is still 0. Oops! Reciprocal of 0 (n/0) is undefined! A vertical line has undefined slope, the horizontal line has slope of 0.
What is slope of 0?
if you define y = constant then the slope of any constant is 0 so if you define the line y = 0 the slope of 0 is 0.
How do you find the product of two numbers when the numerator is 0?
If the numerator is 0 then, provided the denominator is not 0, the answer is always 0.
What is the slope of a line with the points 0 0 and 0 -3?
The slope is undefined.
What kind of line has no x-intercept?
A horizontal line parallel to x axis (slope = 0)
What if there is nothing in the numerator but something is in the denominator?
It is not possible to have nothing. If you don't have anything in numerator, it will be 0 (zero) by default. And when there is 0 in numerator, it doesn't matters what number is in denominator because the answer will be 0 only. So if there is nothing in the numerator but something is in the denominator, the answer will be 0.
