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] ( … 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:

WebJul 25, 2024 · An example of a system of two linear equations is shown below. We use a brace to show the two equations are grouped together to form a system of equations. \[\begin{cases}{2 x+y=7} \\ {x-2 y=6}\end{cases}\] A linear equation in two variables, like 2x + y = 7, has an infinite number of solutions. Its graph is a line. WebUnit 2 Graphing Linear Equations Unit 2 Parallel lines – Parallel lines- lines that have THE SAME SLOPE.They will NEVER intersect. Example: Perpendicular lines- two lines that intersect at a 90° angle. Slopes of perpendicular lines: Are OPPOSITE RECIPROCALS Example: 2.05 Slope Intercept Form Vocab Slope intercept form – A linear equation in … WebFor y − 2 = 3x: the slope is 3, and y-intercept is 2 So they are the same line and so are not parallel Perpendicular Lines Two lines are perpendicular when they meet at a right angle (90°). To find a perpendicular slope: In … the other woman daniel silva
