What is the slope of the line graphed on the coordinate plane? A graph with a line running through coordinates (0, 6) and coordi
dedylja [7]
<h2>Answer</h2>

The slope of the line is -8

<h2>Explanation </h2>

To find the slope of our line we are going to use the slope formula:

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

where

m is the slope of the line

(x_{1},y_{1}) are coordinates of the first point

(x_{2},y_{2}) are the coordinates of the second point

We know that the first point on our graph is (0, 6), so x_{1}=0 and y_{1}=6. We also know that the second point is (1, -2), so x_{2}=1 and y_{2}=-2. Let's replace those values in our formula:

m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}

m=\frac{-2-6}{1-0}

m=\frac{-8}{1}

m=-8

We can conclude that the slope of the line passing through the points (0, 6) and (1, -2) is -8.

Write a proportion to find how many points x a student needs to score on a test worth 50 points to get a test score of 78%.
olganol [36]
The answer is:  "39 points" .
_______________________________________________________
Explanation:
_______________________________________________________
" x/ 50 = 78/100 " ;   in which "x" equals the number of points needed.

_______________________________________________________

To solve for "x" ; 
_______________________________________________________

Look at the denominators:  50 * (what value?) = 100.

→ "100 ÷ 50 = 2" .

→ So;  "50 * 2 = 100" ; 

So, let us look at the numerators:

x * 2 = 78 ; 

↔  2x = 72 ; 

Divide each side of the equation by "2" ; to isolate "x" on one side of the equation ; and to solve for "x" ;
_____________________________________________
 →  78 ÷ 2 = 39 ;

The answer is:  "39 points" .
