What is the slope of a line that passes through the points (-5,-3) and (9,-6)
kipiarov [429]
To find the slope given two points, you need to subtract the two y values over the two x values
(-5,-3)  (9,-6)
-5 will be x1, and -3 will be y1. 9 will be x2, and -6 will be y2. You then need to put the numbers in the correct place in the equation.
y2-y1      -6-(-3)     -9
-------- =   -------- =  ----
x2-x1       9-(-5)     14
Now that we have the slope (-9/14) you can use one of the coordinates to find the value of b.
Let's use (9,-6).
-6=-9/14(9)+b
-6=-81/14+b
+81/14
b=-3/14
Your final equation is y=-9/15x-3/14

0.7x+6=0.3(4x+6)−2x
Gelneren [198K]

Answer: x=-2.8

Step-by-step explanation:

Given the following equation:

0.7x+6=0.3(4x+6)-2x

You can follow these steps in order to solve for "x" and find its value:

1. Apply Distributive property on the right side of the equation:

0.7x+6=0.3(4x+6)-2x\\\\0.7x+6=1.2x+1.8-2x

2. Subract 0.7x from both sides and add the like terms:

0.7x+6-(0.7x)=1.2x+1.8-2x-(0.7x)\\\\6=-1.5x+1.8

3. Subtract 1.8 from both sides:

6-(1.8)=-1.5x+1.8-(1.8)\\\\4.2=-1.5x

4. Finally, divide both side of the equation by -1.5:

\frac{4.2}{-1.5}=\frac{-1.5x}{-1.5}\\\\x=-2.8
