So gradient (slope) $->m = -2$
$y_("intercept")->c=9/7$

Subtract $14x$ from both sides

$7y=9-14x$

Divide both sides by 7

$y=-14/7x+9/7$

$y=-2x+9/7$

Compare to $y=mx+c$ where m is the gradient and the y-intercept is c.

So gradient (slope) $->m->-2$
$y_("intercept")->c=9/7$

What is the slope and y-intercept of this line 14x + 7y = 914x + 7y = 9?
