A vertical line on a graph has infinite slope and no y-intercept. Its equation is [ x = a number ]. The number is the line's x-intercept.
A line in slope-intercept form is: y = mx + b m is the slope of the line, and b is the y-intercept. To find the slope, find any two coordinates, and divide the difference in y-values by the difference in x-values; to find the y-intercept, find the value of y where x = 0.
it is the horizontal line...
Find the value of the trend line when x = 0
The function y = -1 has no x-intercept; its graph is a horizontal line with a y-intercept of -1.
If the x intercept is a and the y intercept is b, then the equation of the line is bx + ay = ab

Find the value of the trend line when x = 0
If the y-intercept does not cross the y-line, then it does not exist, so it cannot be found.
The function y = -1 has no x-intercept; its graph is a horizontal line with a y-intercept of -1.
To find the slope you need to find the Y-Intercept (the line that crosses through the Y-Axis) then on the Y-Intercept move one unit to the right and go either up or down until you've hit the diagonal line.
It is the line that cuts through the y axis
A vertical line does not have a slope - negative or positive. It is not defined. A vertical line has no y intercept and, if its equation is x = c (for some number c), then the x-intercept is (c, 0).
y = {slope}x + {y intercept}
By using the straight line equation of y = mx+c whereas m is the slope and c is the y intercept
