If you actually draw the coordinates, it should be a parallelogram.
The vertices of triangle QRS have coordinates Q(1, −2), R(3, −2), and S(2, −4). The coordinates are the coordinates of the vertices of triangle QꞌRꞌSꞌ when triangle QRS is reflected across the x-axis <span>Qꞌ(1, 2), Rꞌ(3, 2), Sꞌ(2, 4). The answer is letter B.</span>
btw my name is not Google, but I'll post anyhow.
if all three friends only have 5lbs of flour only and therefore only 19 cups of flour, well, each batch takes up 2 cups of flour and they only have 19 cups, 19/2 gives us 9 with a remainder of 1.
so 9 whole batches.
m is the slope
b is the y-intercept
so that means that the y-intercept of
is
Subtract 60 on both sides to get -40.
You are left with 40x=-40
Divide both sides by 40 to leave x by itself.
You get x=-1.
