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.

2/5n+7=12 please go step by step
ryzh [129]

Answer:

n = 25/2

Step-by-step explanation:

First, you would want to subtract 7 from both sides of the equation.  That would cancel the 7s out and 12-7 = 5. So now the equation looks like this: 2/5n = 5.  Next, you would multiply both sides by 5/2, which is the reciprocal of 2/5. Now you have n= 5*(5/2). Lastly, you would just want to multiply 5*5 to get 25 and the 2 will just stay the same. So n = 25/2.
