Firstly, (x+y) squared is x2 + 2xy + y2 so if that is to equal x2 + y2 it follows that 2xy is zero, so either x=0 or y=0 or both are 0. It's also possible to read the question as x2 + y = x2 + y2 so then y=y2 so y= 0 or 1 in that case, with x being anything you like.
It is a straight line equation whereas m is the slope and b is the y intercept.
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 shifts downward (negative y) by 9 units.
ax + by = cThe graph if that equation is a straight line whose slope is (-a/b)and whose y-intercept is (c/b).
It is a straight line equation whereas m is the slope and b is the y intercept.
The equation you have given, y + 2 = 7, does not describe a line, it describes the number 5. You would not graph a single number, there is nothing to graph.
35
It is a straight line.
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.
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.
You are describing a circle, with its center at the origin and a radius of 4 (the square root of 16)
A linear equation ?
The slope of the graph of that equation is -1.
