Question

Draw the graph of each of the following linear equations in two variables: (i) (ii) (iii) (iv)

Philoid · Accepted Answer

(i) Given equation: x + y = 4

Put x = 0 hence, y = 4

Put x = 4 hence, y = 0

X	0	4
Y	4	0

_{(ii) x – y = 2}

_{Put x = 0 hence, y = -2}

_{Put x = 2 hence, y = 0}

X	0	2
Y	-2	0

_{(iii) y = 3x}

_{Put x = 0 hence, y = 0}

_{Put x = 1 hence, y = 3}

_x	₀	₁
_y	₀	₃

_{(iv) 3 = 2x + y}

_{Put x = 0 hence, y = 3}

_{Put x = 1 hence, y = 1}

X	0	1
Y	3	1
