Solving linear systems with graphing
WebThe equation under consideration is y=-x² + 6, so let's take a look at it and see if we can do some basic analysis to figure out what properties the graph might have. The function is a … WebExample: Solve the system by graphing. y = 0.5 x + 2 y = − 2 x − 3. The two equations are in slope-intercept form. The first line has a slope of 0.5 and a y -intercept of 2 . The second line has a slope of − 2 and a y -intercept of − 3 . Graph the two lines as shown. The solution is where the two lines intersect, the point ( − 2, 1) .

WebPractice 1. Use the graph method to solve the system of equations below $$ y = 2x +1 \\ y = 4x -1 $$ WebGood evening. One way would be to substitute the y in Your first equation with the entire right-hand side of Your second equation (which, as You can see, is equal to y): `y = -2x + 10 : now substitute y for x - 1. x - 1 = -2x + 10 : add 2x + 1 to both sides. 3x = 11 : divide both sides by 3. x = 11/3. Use that value to solve for y using one of ...
