Change the equation to slope intercept form and identity the slope and y-intercept -8x+2y=6

Mathematics

gulaghasi [49]3 years ago

The answer is:

y=4x+3

The slope is: 4

The y-intercept is: 3

The explanation is shown below:

1. The slope intercept form of the linear equation is:

y=mx+b

Where m is the slope and b is the y-intercept.

2. Therefore, you must solve for <em>y</em>, as following:

-8x+2y=6\\y=\frac{8x+6}{2}\\y=4x+3

m=4\\b=3

<u>Answer:</u>

y = 4x + 3

<u>Step-by-step explanation:</u>

We are given an equation of a line: -8x+2y=6 and we are to change it to slope intercept form.

The standard slope intercept form of an equation of a line is:

y=mx+c

So changing the given equation to this form.

-8x+2y=6

2y= 6+8x

y= \frac{6}{2} +\frac{8x}{2}

y=3+4x

y=4x+3

y = 4x + 3 is the slope intercept form of -8x + 2y = 6 where 4 is the slope and 3 is the y-intercept.

A line has a slope of 3 and passes through the point (-3, 8). What is the equation of the line​
mixer [17]

Answer:

y=3x+17

Step-by-step explanation:

Slope formula y2-y1/x2-x1=m

y=3x+b

Find b (y-intercept), enter the given coordinates (-3, 8)

8=3(-3)+b

8=-9+b

b=17

y=3x+17

Answer:

(C) 220

Step-by-step explanation:

Let x represent the number of adult tickets sold and y represent the number of student tickets sold. With the information given, we can set up two equations:

x+y=360

5x+3y=1360 (Since for every adult ticket sold, $5 is made and for every student ticket sold, $3 is made)

In the first equation, we can represent x in terms of y:

x=360-y

And then, we can substitute x in the second equation for 360 - y to get:

5(360-y)+3y=1360 which simplifies to:

1800-2y=1360 and therefore, y=220.

Hope this helps :)

A car wash washes 68 cars in 8 hours. At this rate, how many cars are washed in 1 hour?
myrzilka [38]

Answer:

8.5 (If just pure cars then 8.)

Step-by-step explanation:

To find this, just divide 68/8 to find how many cars are washed in an hour. Plugging it into a calculator, we find out that it is 8.5. If you need elaboration, just comment.

For altitudes up to 36,000 feet, the relationship between ground temperature and atmospheric
Verizon [17]

Answer:

The equation for a is a=-\frac{2000}{7}*(t-g)

The altitute is 101,428.57 feet

Step-by-step explanation:

You know that the relationship between ground temperature and atmospheric  temperature can be described by the formula

t = -0.0035a +g

where:

  • t is the atmospheric  temperature in degrees Fahrenheit
  • a is the altitude, in feet, at which the atmospheric temperature is  measured
  • g is the ground temperature in degrees Fahrenheit.

Solving the equation for a:

-0.0035a +g=t

-0.0035a= t - g

a=\frac{t-g}{-0.0035}

a=-\frac{2000}{7}*(t-g)

<u><em>The equation for a is </em></u>a=-\frac{2000}{7}*(t-g)<u><em></em></u>

If the atmospheric temperature is -305 °F and the ground temperature is 50 °F, then t= -305 °F and g= 50 °F

Replacing in the equation for a you get:

a=-\frac{2000}{7}*(-305-50)

a=-\frac{2000}{7}*(-355)

a= 101,428.57

<u><em>The altitute is 101,428.57 feet</em></u>
