Which statement is true?

Question

If the x-intercept of a line is given by (0, b), b can never equal zero. A line of x = a (where a is not zero) cannot have a y-intercept. If the y-intercept of a line is given by (a, 0), a can never equal zero. A line with a zero slope cannot have a y-intercept.

Answer 1

"A line of x=a (where a is not zero) cannot have a y-intercept"  is true.

 

1) x intercept would be (b,0) and b could be 0.

2) "A line of x=a (where a is not zero) cannot have a y-intercept" is true.

3) y intercept would be (0, a), although usually it is denoted by (0, b) since y = mx + b is the slope-(y) intercept formula.

4) A line with a zero slope will always have a y-intercept.

It would never have an x-intercept.
