A line contains the points (8, 5) and (6, 15).
Olenka [21]

Answer: -5

Step-by-step explanation:

The formula for calculating the slope of a line is given as :

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

x_{1} = 8

x_{2} = 6

y_{1} = 5

y_{2} = 15

substituting into the formula , we have

m = \frac{15-5}{6-8}

m = \frac{10}{-2}

m = -5

Therefore the slope is -5

X+3y=9. graph using slope and y-intercept
timama [110]
Well, in order to first determine the slope or y-intercept, you must put change the equation to this format: y=mx+b.
m=slope and b=y-intercept
I
in order to do that, you must change this equation.

x+3y=9

-x     -x
----------
3y=9-x

Then, rewrite it as: 

3y=-x+9
_______
3      3

simplify to  

y=-x/3 +9
