Linear EquationName: ______________________________Class: _________20Chapter<br />Worksheet 2<br />The relationship between the variables x and y is given by the equation y = x + 2 Using suitable scales on the x- and y-axes, plot the graph of y = x + 2 for –3 ≤ x ≤ –2.<br />To plot the graph:- Choose three values for x.  (For example, x = 0,  x = 1,  x = 2.)- Work out the corresponding values for y.- Plot the points on a graph.- Join the points with a straight line.- Label the line with its equation.<br />                y = x + 2x012y<br />y<br />5<br />4<br />3<br />2<br />1<br /> –2 –3      –4 –50–1 x43521<br />–1 <br />–2 <br />–3 <br />–4 <br />–5<br />,[object Object], <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />Figure CFigure AFigure B <br /> <br /> y x y x y x<br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />Figure DFigure FFigure E <br /> <br />Which of the above could be the graph of <br />y = –4,Ans:Figure ____________<br />y + x – 1 = 0, Ans:Figure ____________<br />x = -2Ans:Figure ____________<br /> (d)x – 7 = 0Ans:Figure ____________<br /> (e)y = 5.5 Ans:Figure ____________<br /> <br /> <br />,[object Object],x = 4,   y – 6 = 0,   y = –4,  x + 6 = 0<br />(b)Name the figure formed by these four lines.<br />(c)Write down the coordinates of the vertices of the figure.<br />Use the equations given below to complete the tables.
