there is nothing being added or multiplied to it, and it is on its own side of the equal sign
You can be certain if the equation is linear, that is, of the form ax + b = 0 where a and b are constants.
A line is represented by an equation. Each solution of the equation is a point on the line, and each point on the line is a solution to the equation. So the line is just the graph of the solution set of the equation.
It depends on your equation. Your equation will tell the proportionallity and then will we be able to tell what will happen to the other variables and or just one variable.
Y
You can tell which is the independent variable and which is the dependent variable by changing the equation into an "if/then" statement. Example: y = 3x In this example, x is the independent variable and y is the dependent variable. If you give me x, I will tell you y. If x = 1, then y = 3 If x = 2, then y = 6 So you give me the independent variable, and then I will be able to determine the dependent variable.
The idea is to replace one variable in the equation by the first number in the ordered pair, the other variable with the second number in the ordered pair, do the calculations, and see whether the resulting expressions are indeed equal.
It tells you what values of x give a result of zero. Graphically, they represent the x-intercepts. It might tell you after how many seconds a ball hits the ground after being thrown in the air.
Tell whether the equation -4x+ 2y = -2 represents a direct variation. If so, identify the constant of variation.
A quadratic equation can have a maximum of 2 solutions. If the discriminant (b2-4ac) turns out to be less than 0, the equation will have no real roots. If the Discriminant is equal to 0, it will have equal roots. But, if the discriminant turns out to be more than 0,then the equation will have unequal and real roots.
The word linear means in a straight line. If the graph is a line, it is linear. Also, linear equations are of the first order; they contain a variable but not a square (or higher power) of a variable. If the equation contains x2 it is not linear.
actually....the x are the independent variable,and the y is the dependent variable. the value of y depends on the value of x. tell me I still did not answer this question.the 4 basic numbers are -2,-1,0,1,2. actually I mean 5. apply it in any equation. example:3x=2y+9 x -2 -1 0 1 2 y try to answer that ising the 5 basic numbers. use linear in solving this......transpose if needed! chacha!!!!have fun i solving this cheap question. listen to your teacher and you will never look at here again.
You cannot.
