Gradient (slope) is $5/42$

$color(blue)("By sight: slope is "5/42)$

'~~~~~~~~~~~~~~~~~~~~~~~~~~
$color(blue)("By algebraic manipulation")$

Multiply both sides by (-1) giving to give us a positive $y$

$-32=42y-5x$

Add $5x$ to both sides

$42y=5x-32$

Divide both sides by 42

$y= 5/42x-32$

The coefficient of $x" is "5/42$
