Find the equation of a line parallel to y'= -8x+6.
Verizon [17]

Answer:

The equation must include -8 as the slope

Step-by-step explanation:

Hi there!

Two key points to keep in mind:

  1. Linear equations are typically organized in slope-intercept form: y=mx+b where m is the slope and b is the y-intercept (the value of y when x is 0).
  2. Parallel lines always have equal slopes

Given the equation y=-8x+6, we can identify that -8 is in the place of m in y=mx+b, making it the slope.

For a line to be parallel to y=-8x+6, it would have to have a slope of -8 as well. This is the only quality a line needs to be parallel to this given line.

I hope this helps!

From given picture we can see that X is mid point of line PQ

So PQ=2PX

From given picture we can see that Y is mid point of line PR

So PR=2PY


Now consider triangles PRQ and PYX

Sides PQ and PX has same ratio as of sides PR and PY (as calculated above)

angle XPY= angle QPR  (common angle)

Hence triangles PRQ and PYX are similar.

We know that ratio of the sides of similar triangles is always equal so we can write:

\frac{PQ}{PX} = \frac{QR}{XY}

Plug the given values QR=8 and PQ=2PX

\frac{2PX}{PX} = \frac{8}{XY}

\frac{2}{1} = \frac{8}{XY}

2 = \frac{8}{XY}

XY = \frac{8}{2}

XY = 4

Hence final answer is XY = 4 units.
