Write y= 2/3 x +7 in standard form using integers

Mathematics
1 answer:
Shalnov [3]3 years ago
5 0

Answer:

The standard form of y= \frac{2}{3} x +7   is  -2 x + 3 y  =  21.

Step-by-step explanation:

Here, the given expression is :  y= 2/3 x +7

The standard form of the equation is ax + by  = c

Now, simplifying the above expression:

y= \frac{2}{3} x +7  \implies   y - 7 =   \frac{2}{3} x

or, 3(y-7)  = 2x  \implies  3y - 21 = 2x

or, -2x + 3y  =  21

Hence, the standard form of y= \frac{2}{3} x +7   is -2x + 3y  =  21.

Keeping in mind that, there are 5280 feet in 1 mile and 60 minutes in 1 hour.

\bf \cfrac{80~\underline{mile}}{\underline{hr}}\cdot \cfrac{5280~feet}{\underline{mile}}\cdot \cfrac{\underline{hr}}{60~min}\implies \cfrac{80\cdot 5280~feet}{60~min}\implies \cfrac{422400~feet}{60~min}

Write a equation of a line perpendicular to the line below in point-slope from that passes through the point (-2,6)
STatiana [176]

Answer:

Option 1: y-6=-4(x+2)

Step-by-step explanation:

Find the slope of the perpendicular line by finding the negative reciprocal of the original slope. (Negative reciprocal = flip upside down and add a negative). So we get -4 for the perpendicular slope.

Next, we know the point (-2,6) is on the line, so we can get x=-2 and y=6.

Plug this into point-slope form: y_{1}-y_{2}=m(x_{1}=x_{2})

y_{1} - (6)=-4(x_{1}-(-2))

y-6=-4(x+2)
