NettetThe third answer of (-4,8) is correct. Since both equations are equal to y. You can set them equal to each other instead of the Ys. Then you have x - 2 = 3x + 4. Subtract the x to the 3x to 2x. Then subtract the 4 from the right side of the equation to get -8. Divide by 2 to isolate th x and you get -2. Which you can plug into both equations to ... NettetAlgebra Graph y=3x-4 y = 3x − 4 y = 3 x - 4 Use the slope-intercept form to find the slope and y-intercept. Tap for more steps... Slope: 3 3 y-intercept: (0,−4) ( 0, - 4) Any line …

NettetAnd since the y y -intercepts are different, we know the lines are not on top of each other. There is no solution to this system of equations. Example system with infinite solutions We're asked to find the number of solutions to this system of equations: \begin … NettetThe system has no solution Parallel lines have no intersection, so there are no solutions infinitely many solutions Same slope and intercepts, intersects at infinitely many points Solve y = 2x +5 & y = 2x - 3 No solution - Parallel lines (same slope, different y-intercepts) Solve y = x - 2 & 2x - 2y= 4 orgain bell tucker beaumont

NettetAlgebra 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) Nettetderive the equation y = mx for a line through the origin the equation and y = mx + b for a line intercepting the vertical axis at b. NY.8. F.1 Understand that a function is a rule that assigns to each input exactly one output. The graph of a function is the set of ordered pairs consisting of an input and the corresponding output. NY.8. Nettet24. okt. 2024 · The equation is the relationship between variables and represented as y = ax + b. Here, A. The y-intercept is -7. The equation y = 3x - 7 is in slope-intercept … orgain at cvs
