How could you write the equation of a line that would be parallel to y = -3x - 2 but not share any points
To write the equation of a line that is parallel to y = -3x - 2 but does not share any points, we can use the same slope as the given line (-3), but select a different y-intercept.
Let's denote the y-intercept as b. Since y = -3x - 2 has a y-intercept of -2, we can choose any value for b that is not equal to -2.
For example, let's say we choose b = 4. The equation of the parallel line would be y = -3x + 4.
Another example could be b = 0, resulting in y = -3x.
By selecting a different y-intercept, we ensure that the parallel line does not intersect with y = -3x - 2.
To write the equation of a line that is parallel to y = -3x - 2 but does not share any points with it, you would need to keep the slope the same and change the y-intercept.
The slope of the given line is -3, and since it needs to be parallel, the slope of the new line should be -3 as well. The y-intercept is -2, so you need to choose a different value for the y-intercept.
Let's say we want the new line to have a y-intercept of 4. To find the equation, we can use the slope-intercept form:
y = mx + b
where m is the slope and b is the y-intercept.
Substituting the values, the equation of the line parallel to y = -3x - 2 with a y-intercept of 4 would be:
y = -3x + 4
To write the equation of a line that is parallel to another line, we need to follow two steps:
Step 1: Understand the slope of the given line.
The given line equation is y = -3x - 2. In this equation, the coefficient of x (-3) represents the slope of the line. So, we know that the slope of the given line is -3.
Step 2: Write the equation of the parallel line.
Since we want a line parallel to the given line but not sharing any points, we need to choose a different y-intercept. Let's call the new y-intercept b.
The equation of a line can be written in the form y = mx + b, where m is the slope and b is the y-intercept. Since we want a line parallel to y = -3x - 2, the slope of the parallel line will also be -3. Therefore, the equation of the parallel line would be y = -3x + b.
Now, to ensure that the parallel line does not share any points, we need to choose a different y-intercept (b) than the original line. For example, let's say we choose b = 1. Therefore, the equation of the line parallel to y = -3x - 2 but not sharing any points would be y = -3x + 1.
Keep in mind that there are infinitely many parallel lines to y = -3x - 2 that do not share any points, as long as you choose a different y-intercept for each line.
