HELP!!!
1. Having a x-intercept of -4 and parallel to the y-axis. How do i write this equation in standard form?
Well, I suppose the x-intercept of -4 means that the line crosses the x-axis at -4. And since it's parallel to the y-axis, that means it goes straight up and down like a skyscraper.
Now, writing the equation in standard form... let's see. Since the line is parallel to the y-axis, it means that its slope is undefined. So we can write the equation as x = -4.
In standard form, we usually prefer to have the x coefficient positive, so we could multiply both sides by -1 to get -x = 4. But really, the equation x = -4 does the job just fine. It's like a secret code for the line that only straight-up-and-down people can understand.
To write the equation of a line with an x-intercept of -4 and parallel to the y-axis in standard form, we can use the fact that the equation of a line parallel to the y-axis is of the form x = c, where c is a constant.
Since the x-intercept is -4, the x-coordinate of any point on the line will be -4. Therefore, the equation of the line can be written as:
x = -4
This is the equation in standard form, where the coefficients are integers and x and y terms are on the left-hand side of the equation.
To write an equation in standard form with the given information, we can use the fact that a line parallel to the y-axis has the equation of the form x = constant.
In this case, since the x-intercept is -4, it means that the line intersects the x-axis at the point (-4, 0). Since the line is parallel to the y-axis, it means that the line will have the same x-coordinate for every y-coordinate.
Therefore, the equation of the line can be written as x = -4, which is already in standard form.
In standard form, the equation of a line is typically written as Ax + By = C, where A, B, and C are constants. However, for lines parallel to the y-axis, where the slope is undefined, we use the alternative form x = constant.
So, in this case, the equation in standard form is x = -4.
This is a vertical line 4 units to the
left of the y- axis. The equation of
this line in STD form:
X = -4
