Write an equation of a line which is passing through the point (8, −6) and is parallel to another line, whose slope is −2

ANSWER:  

The equation of the line passing through the point (8,-6) and parallel to line with slope -2 is 2x + y -10 = 0.

SOLUTION:

Given, a line is passing through the point (8, −6) and is parallel to another line, whose slope is −2

We need to find the equation of the line.

We know that, parallel lines will have same slope.

So slope of the required line is -2.

Now, we have a point on the line and slope of the line, so we can use point – slope form to find the line equation.

Point slope form is given as

Where "m" is the slope and is a point on that line.

Here,

Now, substitute values in point slope form.

y – (-6) = -2(x – 8)

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

y + 6 = -2x + 16

2x + y +6 -16 = 0

2x + y -10 = 0

Hence, the equation of the line is 2x + y -10 = 0.

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
