find the slope intercept form of a vertical line passing through (1.5,1.9)
Slope-intercept form is
y = mx + b
where m is the slope and (0, b) is the point on the y-axis
where the line crosses the y-axis, called the y-intercept.
The slope of a VERTICAL line, however, is UNDEFINED!!!
The equation of the vertical line through (1.5, 1.9) is
x = 1.5
However, this is not in "slope-intercept form" because a
vertical line has no slope, it cannot be written in
slope-intercept form.
All other lines besides vertical ones have slopes.
The slope of a horizontal line is 0. A HORIZONTAL, not
vertical line through (1.5,1.9) is
y = 1.9
which can be written is slope-intercept form as
y = 0x + 1.9
But there is no answer to your question. You're
probably supposed to answer:
"It has no slope-intercept form because the
slope of a vertical line is not defined"
