What is the slope of the line contaning (-1,5) and (2,-4)

Simplified: -3

Step-by-step explanation:

So here we will do rise over run which is

So here we have the points (-1,5) and (2,-4), lets plug these in!

Since we are subtracting a negative from a positive it would be simpler and a lot better if we were to turn that into

Now we do the equations!

-4-5= -9

2+1=3

Plug these in! Note that since the nine is negative, the whole thing will be!

Simplify:

-3

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
