Sep 25, 2017 · The graph of the equation 2x - y = 2 will be a straight line passing through the points (0, -2), (1, 0), and (-1, -4). We have, To graph the equation 2x - y = 2, we can start by rearranging it in the slope-intercept form, y = mx + b, where m represents the slope and b represents the y-intercept.

If x and y are real and x^2 + y^2 = 1, compute the maximum value of (x+y)^2. https://math.stackexchange.com/questions/1929678/if-x-and-y-are-real-and-x2-y2-1-compute-the-maximum-value-of-xy Trig-free solution: If x^2+y^2=1 then (x+y)^2 + (x-y)^2 = 2(x^2+y^2)=2 so the largest value of (x+y)^2 is 2, attained when x=y.

Jul 31, 2020 · Equation 2x-y=2. To Find: One of the solution from the given options ( Missing in the question) a) (2,2) b) (5,2) c) (2,5) d) (5,5) Solution: Solution of an Equation satisfy the Equation. Step 1: Substitute x = 2 and y = 2 for (2 ,2 ) to check whether satisfy or not. 2x - y = 2. 2(2) - 2 = 2. 4 - 2 = 2. 2 = 2. TRUE. Hence ( 2, 2) is Solution Of ...
