think about it. The y-axis has equation
x=0
so, any line parallel to the y-axis, say, c units away, will have the equation
x = c
Your point is (4,5), so the line you want is
x = 4
Its slope is undefined, since x never changes. The line is vertical.
Draw the line through the point (4,5)that is parallel to the y-axis. Write the equation of this line and state its slope.
Can anyone assist me. The example or instructions is not in my text.
