What is the formula for slope of a straight line?
the formula for slope is y=mx+b, a horizontal line has the slope of zero and the slope of a vertical line can be answered as undefined
How do you find if a graph is proportional?
It is a straight line through the origin, with a positive slope.It is a straight line through the origin, with a positive slope.It is a straight line through the origin, with a positive slope.It is a straight line through the origin, with a positive slope.
A straight line on a graph means there is a what relationship?
A direct relationship if the slope of the line is positive. An inverse relationship if the slope of the line is negative.
How do you tell whether the relationship between two variables is linear?
By definition, if you graph the relationship between two variables and the result is a straight line (of whatever slope) that is a linear relationship. If it is a curve, rather than a straight line, then it is not linear.
Slope of a straight line?
rise over run
What type of correlation is a straight line with no slope?
The straight line with no slope is a point
How can you tell if a slope is zero or undefined?
A slope is 0 if it is a straight horizontal line. A slope is undefined if it is a straight vertical line.
Why can all linear equations that describe functions be written in point slope form?
Because a linear equation is, by definition, a straight line. Any line can be defined by selecting any one point on the line and the slope of the line.
The slope of a curved line differs from that of a straight line in that?
Slope of a straight line is the same at all points on the line, whereas for a curved line it changes.
What is the formula for slope of a straight line?
the formula for slope is y=mx+b, a horizontal line has the slope of zero and the slope of a vertical line can be answered as undefined
Is the slope of a line the same for the entire line?
If it is a straight line, then yes.
What is the slope of straight line?
0 degrees.
What is the slope of a straight line called?
gradient
What does the slope measure?
The gradient of the straight line

Do undefined slopes have a slope?
An undefined slope is just a line straight down. The slope is undefined.
What is the difference between a line that has zero slope and one that has undefined slope?
A line with zero slope is a straight horizontal line which neigher climbs nor descends along the X-Axis. A line with an undefined slope is a straight vertical line that does not move left or right along the Y- Axis.
