graphing using a table example graph the equation y x 3 here we selected values for x to be 2 4 and 6 you could have chosen any values you wanted graph the equation y x 3 jennarocca 2 solving systems graphical method step 1 graph both equations step 2 find the point of intersection y x x 2y 7 x y 4 x yx y 0 3 ½ 0 4 1 3 1 3 graph the equation y x 3 jennarocca 6 graph creategraph2qq determine the slope and y intercept of y x 1 and graph the equation 5 3 3 2 graph graph the pair of the parametric equation x 3 sin3t y 3 cos3t from the graph we can see that both functions coincide where x 5 and x 1 the solutions correspond to the points of intersection horizontal and vertical lines question use the graph of f x x3 to write an equation for each function whose graph is shown 9 notes over 2 8 writing an absolute value function vertex axis of symmetry slope 3 0 x 3 down 3 right left 2 write an equation of the graph if the orginal equation is changed to factored form we have y x 85 x 2 35 if y is changed to 0 and the zero property is used graph of linear equation in two variable tutoring homework help use intercepts to graph an equation example 2 step 2 guided practice for examples 2 and 10 7 0 5 20 3 1 5 xy 1 graph important types of graph describe the rule of four as applied to the equation y 1 4 x 3 7 example 2 use the graph and check method solve the linear system x y 7 equation 1 x 4y 8 equation 2 solution step 1 graph both equations this is a graph of a line on an x y coordinate plane the draw the graph of the equation x 3 y 4 1 also find the area of the triangle formed by the l important questions for cbse class 9 mathamatics linear 3 example 1 warm up 12 11 07 graph each equation and tell whether it is 3 graph an equation draw the graph of the equation x 3 y 4 1 also find the area of the triangle formed by the l 3 x comparison one variable equations two variable equations x y 5 graph the equation x 3 1 graph the equation y x 3 22 your turn graph the equation x 3 answer graph y to graph the equation first plot 5 points on the graph 3 use if ou graph the equation of 2 ln x and you graph the equation of ln x 3 ln x 1 you will find that those graphs will not intersect because the value of if you were given the graph above and asked to write an equation normally you are also given the pa graph y x you know the equation of the 15 graph extra example 1 example 2 solve x 3 0 5x algebraically neither of these equations had a variable with a coefficient of one in this case solving by substitution is not the best method we consider the exemple of the line of equation y 2 x 3 drawing the graph of y x 3 using table and grant intercept method example 2 find the x intercept s and y intercept s graph with the point 0 0 the point 1 2 checkpoint graph a linear equation in three variables
