Recall from Intermediate Algebra that two non-vertical lines are perpendicular if and only if they have negative reciprocal slop
OLEGan [10]

Complete Question

The complete question is shown on the first uploaded image

Answer:

The line is y  =  -4 x

Step-by-step explanation:

From the question we are told that

The line is y  =  \frac{1}{4} x  + 8

The point is P(0,0 )

Generally the equation for a line is yn =  mx  + c

Now comparing this with the given equation we see that

m  =\frac{1}{4} =  slope

C  =8  =  intercept

Generally the slope of the perpendicular to the given line is mathematically evaluated as

m_1  = -  \frac{1}{m}

=> m_1  = -  \frac{1}{ \frac{1}{4}}

=> m_1  = -4

Generally from the univesal equation of a line and the given point we have that

y = mx + c at p(0,0) and m_1 =  -4 is

0 = -4 (0 ) + c

=> c = 0

Hence the equation perpendicular to the line given at the point given is

y  =  -4 x

Goryan [66]
<span>This simply means that your actual tax was 3750 because the total withheld - the refund. A tax refund is not an extra money earned by a person, it is actual an excess of what was paid by the person that the IRS have decided to give back to that person.Taxes are usually deducted based on information declared in Form W-4. The yardstick used by IRS is a straightforward method to lessen your assessable wage, yet you have the choice to ascertain your own ordered findings, utilising your genuine deductible costs.</span>
