Points: (0, 7) and (8, -3) Slope: -5/4
let (x1, y1) = (4, 7) and ( x2, y2) = ( 7, -8). Then, Slope = m = (y2 - y1)/(x2 - x1) m = (-8 - 7)/(7 - 4) m = -15/3
Points: (-1, 8) and (5, -4) and the slope works out as -2
15
If the points are: (0, 3) and (8, -3) then the slope works out as -3/4
The equation of this line is x=8 and it is my understanding that the slope is infinite/undefined.
Slope = rise/run, the run in this case is 0 therefore the slope is "undefined" since you can't devide by zero.
Slope = 7--3 over 0-8 = -5/4
Points: (0, 7) and (8, -3) Slope: -5/4
Points: (8, 3) and (8, 7) Slope: 0 The line is a straight vertical line parallel to the y axis
-1
It is undefined: the calculation involves division by 0.
let (x1, y1) = (4, 7) and ( x2, y2) = ( 7, -8). Then, Slope = m = (y2 - y1)/(x2 - x1) m = (-8 - 7)/(7 - 4) m = -15/3
Points: (8, 3) and (8, 7) Slope: 0 It will be a straight vertical line parallel to the y axis
The slope for these two points is undefined, or straight up.
If the slope is -3 and the point is (-8, -4) then (y - -4) = -3(x - - 8) => y = -3x -28
The slope of a vertical line is undefined and so there cannot be a slope-intercept form of the equation.
