Y = mX + b where
m = slope =0 and b = y intercept
y = b for all values of x
y is a constant for all values of x
yes, the slope of the line is the tangent of the angle
Slope of (2, -4) and (6, -1) is 3/4 Slope of (-7, 1) and (-4, 5) is 4/3 It is a reciprocal relationship
The slope of a line is its gradient
Yes.
It means that the relationship between the x and y variables is not linear.
If a line has a slope m then a line perpendicular to it has a slope -1/m ( negative inverse). For example if a line has slope positive 2, its perpendicular has slope -1/2
yes, the slope of the line is the tangent of the angle
A direct relationship if the slope of the line is positive. An inverse relationship if the slope of the line is negative.
Slope of (2, -4) and (6, -1) is 3/4 Slope of (-7, 1) and (-4, 5) is 4/3 It is a reciprocal relationship
The slope of a line is its gradient
1
The slope of a line is the same thing as the rate of change between two variables in a linear relationship.
intersecting lines
Yes.
It means that the relationship between the x and y variables is not linear.
The slope of a vertical line would be parallel to the y axis.
They are negative reciprocals. So if the slope of a line is x, the slope of the perpendicular line is -1/x
