3xy2=0 2x y=8 simultaneous equationSolve the following simultaneous equation graphically 3x – y – 2 = 0;Lines intersect at coordinates x= 4, y= 16 The only value x can equal is 4 The equation x = 4 is a vertical line that intersects the y axis at coordinates x=4, y=0 Substituting x=4 into the equation y= 2x 8 , y= 2x4 8 = 16Y= x^2 3x 18 We need to find the xintercept of the curve y The xintercept is the point where the curve y meets the xaxis Then the values of y would be zero For y=ax^2bxc the x for vertex is x_v=b/(2a)=3/2 so y_v=x^2−3x8 = (3/2)^23*3/28= 23/4 So the vertex is ( 3/2,23/4) Since a>0, so it is looking up The yintercept is Y=0^23*08=8 so (0,8) After finding the yintercept, we should practically find the xintercept, but as you see, the graph is looking upward since a is bigger than 0 and the vertex is higher than 0
