Question

The diagram shows the points $A(-7,\ 5)$ and $B(5,\ -4)$. Find the length of $AB$,[2] the coordinates of the midpoint of $AB$,[1] the gradient of $AB$,[1] the equation of $AB$.[2]

Accepted Answer

(i) $15\text{ units}$ (ii) $\left(-1,\dfrac12\right)$ (iii) $-\dfrac34$ (iv) $y=-\dfrac34x-\dfrac14$, or $3x+4y+1=0$
