What is y=-2/5x in standard form

VikaD [51]

Standard form is x + y = number.

y = -2/5 x

y + 2/5 x = 0

2/5 x + y = 0

In standard form, the coefficient of x or y cannot be a fraction.

Therefore we have to multiply the whole equation by 5.

2x + 5y = 0

Answer:

$y=-\frac{8}{7}x+4$

Step-by-step explanation:

A line is perpendicular to another if its slope is the negative reciprocal of the other.

Your lines are in slope intercept form here, y=mx+b, where m is the slope. We can see the given line has slope $\frac{7}{8}$ . The negative reciprocal of that is $-\frac{8}{7}$ , which is the slope of the third answer choice.

We have been given that Mr. Luis wants to sell his house. The state he lives in charges a 3.5% sales tax on the sale of a house. The county charges a 3.9% sales tax, and the city charges a 2.2% sales tax.

We are asked to find the total tax, if Mr Luis sells his home for $122,500.

To find total tax, we will add all tax rates as they are being applied to same base.

$\text{Total of tax rates}=3.5\%+3.9\%+2.2\%$
