On the grid below, draw the graph of $y = 4x - 3$, $y = 4x + 8$ for value of $x$ from $-5$ t

Question

On the grid below, draw the graph of $y = 4x - 3$, $y = 4x + 8$ for value of $x$ from $-5$ to $5$. $x=-1$ $x=1$ for value of $y$ from $-15$ to $15$. Write down the gradients of the straight lines in (i). Based on your drawings in (i), identify the geometrical shape enclosed by the four graphs.

Accepted Answer

(i) Graphs of $y=4x-3$, $y=4x+8$, $x=-1$, and $x=1$ (ii) Gradients $4$, $4$, undefined, undefined (iii) Parallelogram
