Question

$x$$0$$2$$4$ $y$$-5$$-1$$p$ The table above shows the values of $y=2x-5$. Calculate the value of $p$. Using a scale of $2$ cm to represent $1$ unit on both axes, draw axes for values of $x$ from $0$ to $4$ and for values of $y$ from $-6$ to $3$. On your axes, draw the graph of $y=2x-5$ for $0\le x\le 4$. From the graph, find the value of $x$ when $y=1$. $x$$0$$1$$2$ $y$$0$$-3$$q$ The table above shows the values of $y+3x=0$. Calculate the value of $q$. On the same axes, draw the graph of $y+3x=0$ for $0\le x\le 2$. From the graph, find the solution to the simultaneous equations $y=2x-5$ and $y+3x=0$.

Accepted Answer

(a) $p=3$ (b) graph of $y=2x-5$ through $(0,-5)$, $(2,-1)$, and $(4,3)$ (c) $x=3$ (d) $q=-6$ (e) graph of $y+3x=0$ through $(0,0)$, $(1,-3)$, and $(2,-6)$ (f) $x=1,\ y=-3$
