Jaime cuts a piece of wood for a project. The first cut is shown and can be represented by the equation y=1/3x +4. The second cu
Burka [1]

For this case we have that by definition, the equation of the line of the slope-intersection form is given by:

y = mx + b

Where:

m: It's the slope

b: It is the cut-off point with the y axis

According to the statement we have the following equation:

y = \frac {1} {3} x + 4

Where:

m = \frac {1} {3}

By definition, if two lines are parallel then their slopes are equal.

Thus, the second equation will be of the form:

y = \frac {1} {3} x + b

We substitute the given point and find "b":

-5 = \frac {1} {3} (0) + b\\b = -5

Finally, the equation is:

y = \frac {1} {3} x-5

Option D

We use quadratic formula then

For a expression

  • ax²+bx+c=0

The quadratic formula is

\\ \rm\Rrightarrow x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}

If underroot values becomes negative we use iota(i)

which has value=√-1
