Maths · Straight line: Various forms of equations of a line, intersection of lines, angles between two lines
Which equation represents the line that passes through the point (-1,4) and is p
Which equation represents the line that passes through the point (-1,4) and is parallel to the \( y \) -axis?
- A. \( y=-1 \)
- B. \( x=-1 \)
- C. \( x=4 \)
- D. \( y=4 \)
Step-by-step solution
A line parallel to the y-axis is vertical, expressed as x = constant. Since it passes through (-1,4), the x-coordinate is -1, so the equation is x = -1.
