Write the equation of a line in point-slope form that is parallel to the line y = 3x +6 and passes through the point (-5, 8)

1 answer:

8 0

Answer: y-8 = 3(x+5)

--------------------------------------------------------------

Explanation:

The slope of the given line y = 3x+6 is m = 3
Anything parallel to this will also have the same slope (of m = 3)

The given point is (-5,8), so this means (x1,y1) = (-5,8)
further breaking down to x1 = -5 and y1 = 8

The three pieces of info we have are: m = 3, x1 = -5 and y1 = 8
Which are then plugged into the point-slope form below
y-y1 = m(x-x1)
y-8 = 3(x - (-5))
y-8 = 3(x+5) ... make sure to simplify as much as possible

In the event that a line has no y-intercept, that implies it never converges the y-intercept, so it must be parallel to the y-intercept. This implies it is a vertical line, for example, . This slant of this line is vague. In the event that the line has no x-intercept, at that point it never meets the x-intercept, so it must be parallel to the x-pivot.

If x-intercept is -2 the line would be vertical as the y-intercept = 0.
