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
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
A direct relationship if the slope of the line is positive. An inverse relationship if the slope of the line is negative.
The slope of a line is its gradient

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.
A straight line on a graph usually indicates a linear relationship between two variables, in this case, two temperatures. The slope of the line can tell us the rate of change between the two temperatures. If the line has a positive slope, it means the temperatures are positively correlated, while a negative slope indicates a negative correlation.
