WebTo find the linear equation you need to know the slope and the y-intercept of the line. To find the slope use the formula m = (y2 - y1) / (x2 - x1) where (x1, y1) and (x2, y2) are two points on the line. The y-intercept is the point at which x=0. What are the 4 methods of solving linear equations?

Web1 answer To graph the equation y = 3x + 3, we can first make a table of values: x y --- --- -2 -3 -1 0 0 3 1 6 2 9 Then, we can plot those points on a graph and connect them with a straight line: ! [Graph of y = 3x + 3] ( … WebJun 30, 2024 · Graph: y = 3x This equation is in slope intercept form, and can be rewritten as: y = 3x + 0, where 3 is the slope and "0" is the y-intercept. Determine a few points on the line by choosing values for x and solve for y. Points x = ( −2),y = ( − 6) x = 0,y = 0 x = 2,y = 6 Plot the points and draw a straight line through them. children\u0027s rashes spots pictures

WebSolve by Graphing y=-3x+4 y=3x-2 Mathway Algebra Examples Popular Problems Algebra Solve by Graphing y=-3x+4 y=3x-2 y = −3x + 4 y = - 3 x + 4 y = 3x − 2 y = 3 x - 2 Create a graph to locate the intersection of the equations. The intersection of the system of equations is the solution. (1,1) ( 1, 1) WebNov 4, 2024 · A system of linear equations can be solved graphically, by substitution, by elimination, and by the use of matrices. (1) -2x + y = -5 and 3x - 2y = 12 Make y the subject in -2x + y = -5 Substitute in Subtract 10 from both sides Recall that: The solution is (-2,-9) (2) y = x + 2 and 2x - y = -4 Substitute in Add 2 to both sides Recall that: WebWe can graph a the linear equation like 5x + 2y = 20 by rewriting it so y is isolated, then plugging in x values to find their corresponding y-values in a table. We can then graph … gower coastline
