A line passes through the point (0, 1) and has a positive slope. Which of these points could that line NOT pass through? Check a
Vinvika [58]

We have to find slopes one by one.

\\ \sf\longmapsto Slope=m=\dfrac{y_2-y_1}{x_2-x_1}

#1

  • (0,1)
  • (12,3)

\\ \sf\longmapsto \dfrac{3-1}{12-0}

\\ \sf\longmapsto \dfrac{2}{12}

\\ \sf\longmapsto \dfrac{1}{6}>0

  • Line passes through this.

#2

  • (-2,-5)

\\ \sf\longmapsto \dfrac{-5-1}{-2-0}

\\ \sf\longmapsto \dfrac{-6}{-2}

\\ \sf\longmapsto 3>0

  • Line passes through this

#3

  • (-3,1)

\\ \sf\longmapsto \dfrac{1-1}{-3-0}

\\ \sf\longmapsto \dfrac{0}{-3}=0

  • Not possible (Line passes through y axis as one co-ordinate is (0,1))

#4

  • ( 1,15)

\\ \sf\longmapsto \dfrac{15-1}{1-0}

\\ \sf\longmapsto \dfrac{14}{1}

\\ \sf\longmapsto 14>0

  • Line passes through this

#5

  • (5,-2)

\\ \sf\longmapsto \dfrac{-2-1}{5-0}

\\ \sf\longmapsto \dfrac{-3}{5}

  • Line doesnot pass through this.

Someone help please i am so bad at point slope stuff
Fynjy0 [20]
<span>1) Write the point-slope form of the equation of the horizontal line that passes through the point (2, 1). y = 1/2x

2)Write the point-slope form of the equation of the line that passes through the points (6, -9) and (7, 1). 
m = (-9 - 1) / (6 - 7) = -10/-1 = 10
y + 9 = 10 (x - 6)
y = 10x - 69

3) A line passes through the point (-6, 6) and (-6, 2). In two or more complete sentences, explain why it is not possible to write the equation of the given line in the traditional version of the point-slope form of a line. 

4)Write the point-slope form of the equation of the line that passes through the points (-3, 5) and (-1, 4).
m = (5 - 4) / (-3 - -1) = 1/-2
y - 5 = (-1/2) (x +3)
y = (-1/2)x + 7/2

5) Write the point-slope form of the equation of the line that passes through the points (6, 6) and (-6, 1).
m = (6-1)/(6 - -6) = 5 / 12
y - 6 = (5/12) (x-6)
y = (5/12)x + 17 / 2

6) Write the point-slope form of the equation of the line that passes through the points (-8, 2) and (1, -4).
m = (2 - -4)  / (-8 -1) = 6 / -7
y - 2 = (-6/7) (x + 8)
y = (-6/7)x - 50 / 7


7) Write the point-slope form of the equation of the line that passes through the points (5, -9) and (-6, 1).
m = (-9 - 1) / (5 - -6) = -10 / 11
y + 9 = (-10 / 11) (x - 5)
y = (-10 / 11)x -49/11
