28 maj 2023 · Let’s graph the equation y = 2 x + 1 y = 2 x + 1 by plotting points. We start by finding three points that are solutions to the equation. We can choose any value for x x or y , y , and then solve for the other variable.
draw its graph for values of x from −2 to 3. Question 1: (a) Draw y = x + 1 and y = 2x − 1 on the same set of axes. (b) Where do the two graphs intersect? O is the origin. (e) Find the area of triangle OAB. 3: Emma has tried to draw the graph of y = 4x − 5 Can you spot any mistakes?
23 mar 2024 · To solve a system of two linear equations, we want to find the values of the variables that are solutions to both equations. In other words, we are looking for the ordered pairs (x, y) that make both equations true. These are called the solutions to a system of equations.
