The same techniques are used to graph a system of linear equations as you have used to graph single linear equations We can use tables of values, slope and yintercept, or x– and yintercepts to graph both lines on the same set of axes For example, consider the following system of linear equations in two variablesThe easiest way to graph a line is in slopeintercept form multiply by 1 because y must be positive your slope ofGraph the linear equation xy=4 Answers Answer from aprilayleen It's a linear equation so it's going to produce a line xy=4 This means that y=x4 When x=0, y=4 When y=0, x=4 Draw a line that goes through the points (0, 4) and (4, 0) Answer from kyla322 Ok, I would bend over backwards!

7a Graphing Quadratic Functions Practice The axis of symmetry is the xcoordinate vertex of the parabola The general form to find the axis of symmetry is For y =x^2 4x 2, a=1, b=−4 and c=2 If the function is symmetrical about the line x=0, it is an even function, so cannot have any odddegree terms The only viable choice is1) y = x^2 4x 2 First find the axis of symmetry (x= b/(2a)) find the vertex from that and it helps you choose the values for x when you make your x/y tables In this equation a = 1; Y=x^2-4x+1 axis of symmetry
