a student found the slope of a line that passes through the points (1,14) and (3,4) to be 5. what mistake did she make?

mariarad [96]

$x_{1}=1$
$x_{2}= 3$
$y_{1} =14$
$y_{2}=4$
$Slope= \frac{rise}{run} = \frac{ y_{2} - y_{1} }{ x_{2} - x_{1} } = \frac{4-14}{3-1} = \frac{-10}{2} =-5$

answer: The student flipped the y values

1 1/4 subtracted from its reciprocal is :<br> A -9/20. B - 1/20. C 1/5. D - 1/5

dalvyx [7]

Answer:

Step-by-step explanation:

first we turn ur mixed number into an improper fraction

1 1/4 = 5/4

the reciprocal of 5/4 can be found by just flipping it....so the reciprocal is gonna be 4/5

so 1 1/4 subtracted from its reciprocal is :

4/5 - 5/4 =

16/20 - 25/20 =

- 9/20 <====
