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.
A line with a y-intercept but no x-intercept will be a straight line parallel to the x axis. It will have a slope of zero.
The slope intercept form equation is stated as the following: y= mx + b. Where m is the slope or the coefficient in front of the x and b is the y intercept.
Slope is zero y-intercept is -7 there is no x-intercept for this equation
