Answer:
(x,y)=(-13,-12)
Step-by-step explanation:
5x - 7y = 19
7x - 7y = -7 Multiply both sides of the equation by -1
Which then gives you :
5x-7y=19 Sum the equations vertically to eliminate
-7x+7y=7 at least on variable
-2x=26 Divide both sides of the equation by -2
X=-13 Substitute the given value of x into the equation 7x - 7y =-7
7 x(-13)-7y=-7 solve the equation for y
y=-12
Thus gives you (-13,-12)

Answer:
-3
Step-by-step explanation:
slope (m) = (y2 - y1)/(x2 - x1)
(1, 1) --> 1 = x1, 1 = y1
(2, -2) --> 2 = x2, -2 = y2
(-2 - 1) / (2 - 1) = -3 / 1 = -3
therefore, the slope is -3
