First, you should type this equation into your graphing calculator and push the zoom 7-trig button in order to see the graph properly.
The amplitude is the distance from the x-axis to the peak of the curve (the very top or bottom). When you check the table on your graphing calculator, you will see that the y-values only go up until 3 and down until -3 meaning that the graph cannot exceed these y-values.
The x-axis is zero on the y-axis so...
0-3=-3
0-(-3)=3
Distance is always positive so the amplitude is 3 units.
**Make sure to type everything in carefully. Your work can simply include a sketch of the graph and the table of values of the equation. Have fun!
The equation 0 equals 0 is an identity and contributes absolutely nothing to the part of the graph that you should shade or not. The tautological statement can be ignored.
Same way you graph y = -4x - 0.5
Just swap the letter around in the formula that you are given!
the graph is moved down 6 units
The graph shifts downward (negative y) by 9 units.

The equation 2x - 3y = 6 is a linear equation and a linear equation is always has a straight line as a graph
The equation has no slope. The graph of the equation is a straight line with a slope of -1 .
That's not an equation, so there's nothing to graph. Simple way to tell: There's no "equals" sign in it.

A linear equation ?
The slope of the graph of that equation is -1.
