Answer: A line that is parallel to another line has the same slope. The slope of the line x-2y=6 can be found by rearranging it into slope-intercept form, y = mx + b, where m is the slope:

x - 2y = 6

Add 2y to both sides:

x = 2y + 6

Divide both sides by 2:

y = (1/2)x + 3

So the slope of the line x - 2y = 6 is m = 1/2.

Since the line through the point (−6,−8) must have the same slope as the line x-2y=6, its slope is also 1/2. To find the equation of this line, we can use the point-slope form of a line, which is:

y - y1 = m(x - x1)

where (x1, y1) is a point on the line and m is the slope. Substituting the values m = 1/2, x1 = -6, and y1 = -8 into the point-slope form gives:

y - (-8) = (1/2)(x - (-6))

Expanding the right side:

y + 8 = (1/2)x + (1/2)(-6)

y + 8 = (1/2)x - 3

Multiplying both sides by 2:

2y + 16 = x - 6

Adding 6 to both sides:

2y + 22 = x

So the equation of the line that passes through the point (−6,−8) and is parallel to the line x - 2y = 6 is:

2y + 22 = x
