solve the equation for y to get the slope.y=-2x-1/2substitute (3,3) into the equation/3=2(3)+band solve for b.-3=+by=2x-3 is the equation with the same slope(parallel) and goes through (3,3)
If you mean points of (2, -3) and (3, 5) then the equation works out as y=8x-19

Turnaround facts in addition are numbers or parts that can be switched with the answer staying the same. For example 3+4=7 4+3=7 In subtraction the total stays the same in the beginning of the equation and the parts are switched. For example 7-3=4 7-4=3 Good luck
The equation 3 by 3 is 9. This is a math equation.
The balanced equation for sodium reacting with water is: 2Na + 2H2O → 2NaOH + H2
A condensed statement of facts about a chemical reaction is called a chemical equation. It summarizes the reactants, products, and their quantities in a concise format.
It is: y = x+3
A solution to an question makes the equation true. For example a solution to the equation 3x = x + 6 is x = 3, since 3(3) = 3+6.

You can write equations for each of the two facts provided, then solve the equations. If you call the length "l", and the width "w", the facts are:3 more than...: w = 2l+3 perimeter: 2(l+w)=60 This is fairly easy to solve if you replace the first equation in the second (in the second equation, replace "w" by the expression that is on the right, in the first equation).
It is an equation which states that 3*(n/7) = 15It is an equation which states that 3*(n/7) = 15It is an equation which states that 3*(n/7) = 15It is an equation which states that 3*(n/7) = 15
