The problem gives you a point and a "slope": two things that can be used to find the equation of the line.
The slope of the y-axis is undefined. A parallel line to the y-axis will also have an undefined slope. This means your equation will only have an x in it, as in x =.
The only line that runs through the point (4, 1) and is also parallel is x = 4. Notice that the point has the x-coordinate of 4. All the points on this line will have the same x-coordinate.
The equation of the line is x = 4.

If the line is parallel to the y axis, then x is a constant.
So the equation of the line is x = 4.

x =4
if you replace the variables with the coordinates, it's true (4 =4), and if you draw it it's a vert. line, parallel to the y axis

X=4, that is the answer

yea x=4... because the slope is the same... its undefined...so it has to be x equals.... and u know its x=4 because all the xs are going to be the same... only the ys change

x=4
y-1=4(x-4)
y-1=4x-16
y=4x-15
