Step 1: Simplify each side, if needed.
Step 2: Use Add./Sub. Properties to move the variable term to one side and all other terms to the other side.
Step 3: Use Mult./Div. ...
Step 4: Check your answer.
I find this is the quickest and easiest way to approach linear equations.
Example 6: Solve for the variable.
Answer:
+x=-y
Step-by-step explanation:
The answer would be option 1, mass divided by volume
Answer:
The equation of the line would be y = -3x + 7
Step-by-step explanation:
In order to find the equation, we first need to find the slope. We can do this by using the slope equation with the points.
m(slope) = (y2 - y1)/(x2 - x1)
m = (4 - -2)/(1 - 3)
m = 6 /-2
m = -3
Now that we have this, we can use point-slope form along with one of the points to get the equation.
y - y1 = m(x -x1)
y - 4 = -3(x - 1)
y - 4 = -3x + 3
y = -3x + 7
