Given two points, P = (a,b) and Q = (c,d) then provided a ≠c,
slope = (d - b)/(c - a).
If a = c then the slope is undefined.
The equation of a line with an undefined slope is x = a.
you say undefined
-12
if a line has a slope of -2 and a point on the line has coordinates of (3, -5) write an equation for the line in point slope form
Write the equation in slope-intercept form of the line that has a slope of 2 and contains the point (1, 1).
Any vertical line has an undefined slope. The equation of the vertical line is x = a where the x-intercept is a.
y= slope + y-intercept
-1
Write the equation of a line in slope-intercept form that has a slope of -2 and passes through the point (2, -8).
The slope-intercept form of an equation is: y = mx + b Just copy down this equation, then replace "m" with the slope, and "b" with the y-intercept.
Y=mc+b
