1st question,
The point "Q" is 0 horizontally, (x-axis)
and 3 up vertically (y-axis) so it is (0,3)
Hence, we write points like: (x,y)
2nd question,
The slope formula is
\(y_2-y_1/x_2-x_1\) ( / is divided) so pick any 2 points on the slope and use this formula.
Let's pick:
(1,2) , (-1,-2)
-2-2/-1-1 = -4/-2 = 4/2=2 (slope)
also it is rise/run look at the change in x and y, x goes 1 to the right, y goes 2 up
so slope is =2
