So gradient (slope) ->m = -2m=2
y_("intercept")->c=9/7yinterceptc=97

Explanation:

Subtract 14x14x from both sides

7y=9-14x7y=914x

Divide both sides by 7

y=-14/7x+9/7y=147x+97

y=-2x+9/7y=2x+97

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

So gradient (slope) ->m->-2m2
y_("intercept")->c=9/7yinterceptc=97
