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.
