The slope is -4
No. In the coordinate plane, for example, they would result in different lines.
yes
5 and the y intercept is 2

All points whose y-coordinate is twice its x-coordinate.
There is no "equals" sign therefore "x-9" is NOT an equation.
Assuming 6 refers to the value of x, the y coordinate is 1
Well, you take y=mx+b and you fill in the numbers M= slope y= y-coordinate x= x-coordinate
-11
There are infinitely many coordinate pairs - the coordinates of each point on the infinite line defined by the equation.
The slope is -4
To check this, you substitute the values for x and y into the equation. At (1,2) x equals 1 and y equals 2 so substituting this in we get: x + 2y = 1 + 2(2) = 1 + 4 = 5 And since it equals 5 like in the original equation the point is represented by it.
