Determine the point on the graph of the linear equation x y = 6, whose ordinate is 2 times its abscissa asked in Class IX Maths by priya12 Expert ( 748k points) linear equations in two variables Explanation Given x −y = 2 Step 1 Rearrange the equation into standard form Add y to both sides x − yy = 2y ⇒ x 0 = 2 y Subtract 2 from both sides ⇒ x−2 = 2−2 yBefore discussing how to solve a system of linear equations below, it is helpful to see some pictures of what these solution sets look like geometrically One Equation in Two Variables Consider the linear equation x y = 1 We can rewrite this as y = 1 − x, which defines a line in the plane the slope is − 1, and the xintercept is 1
Graph the linear equation by using slopeintercept method The equation x y = 2 Write the above equation in slopeintercept form y = mx b, where m is slope and b is yintercept Now the equation is y = x 2 Slope m = 1 and yintercept b = 2 yintercept is 2, so the line crosses the yaxis at (0, 2) Using slope find the next point \(\begin{array}{l}xy3=0 \\ 2 x5 y1=0\end{array}\) Is a pair or a system of two simultaneous linear equations in two variables x and y A solution to a pair of linear equations in two variables is an ordered pair of numbers that satisfy both equations For the above example, x = 2, y = 1 is a solution to the pair of linear equationsAnswer (1 of 4) Yes!

y=3x2 y4x=9 These are examples of linear equations which is a first degree algebraic expression with one, two or more variables equated to a constant So x=2 is a linear equation as is y=1 but x2 =1 is not since the variable, x , has degree 2A linear equation values when plotted on the graph forms a straight line The general form of a linear equation is ax b = c, where a, b, c are constants and a 0 and x and y are variable For Example x 7 = 12, 5/2x 9 = 1, x 2 1 = 5 and x/3 5 = x/2 3 are equation in one variable x Here the highest power of each equation is oneDetermine if Linear y=x^2 y = x2 y = x 2 A linear equation is an equation of a straight line, which means that the degree of a linear equation must be 0 0 or 1 1 for each of its variables In this case, the degree of variable y y is 1 1 and the degree of variable x x is 2 2 Not Linear
