It is y = 3.
The vertical line that passes through the point (0, 4) is the Y-axis. Its equation isX = 0
You can have infinitely many lines through one specific point, each with a different equation. If you want to have a general equation for ANY line that goes through that point, use the point-slope equation for a line, and use a variable for the slope.
y = 5
y = - 4x - 9
7x-y-28 = 0
The equation of a vertical line passing through the point (-4,0) is x = -4. Since all points on a vertical line have the same x-coordinate, the equation is simply x = -4.
The vertical line that passes through the point (0, 4) is the Y-axis. Its equation isX = 0
You can have infinitely many lines through one specific point, each with a different equation. If you want to have a general equation for ANY line that goes through that point, use the point-slope equation for a line, and use a variable for the slope.
y = 5
There is not a single line, but infinitely many lines, that pass through the point (-5, 0). One thing you can do is choose some random slope, then use the equation for an equation that goes through a point and has a specified slope.
3x - y - 26 = 0
what
y = - 4x - 9
It is: y = 8 which will be a straight line parallel to the x axis
7x-y-28 = 0
The x-coordinate of any point on the y-axis is 0. The y-axis is a line perpendicular to the x-axis. Any point on a line perpendicular to the x-axis has the same x-coordinate. The y-axis is the line perpendicular to the x-axis through 0, and has the equation x = 0; similarly, the x-axis is the line perpendicular to the y-axis through 0 and has the equation y = 0.
If you know that the line passes through the point (0,0) and has a slope of 0.6, then you can use the point-slope formula to find the equation of the line. y - y1 = m(x - x1) becomes y - 0 = 0.6(x - 0) becomes y = 0.6x
