What is the equation of the line that passes through the point (-4, 2) and has a
slope of 1/4?

Answers

Answer: The equation of the line is y=1/4x + 3

Step-by-step explanation:

To get the equation, you have to set it up:

y=1/4x + b

Plug in the coordinates (-4, 2) next:

2=1/4(-4) + b

Solve:

2= -1 + b

add one on both sides:

3= b

Use the information to get the equation:

y=1/4x + 3

Suppose m <6= 147º. Find <1 and m<3

Answers

Answer:

∠ 1 = ∠ 3 = 33°

Step-by-step explanation:

∠ 3 and ∠ 6 are same- side interior angles and are supplementary , thus

∠ 3 + ∠ 6 = 180° , that is

∠ 3 + 147° = 180° ( subtract 147° from both sides )

∠ 3 = 33°

∠ 1 and ∠ 3 are vertical angles and congruent, thus

∠ 1 = ∠ 3 = 33°

What is the result of solving this equation for x?

y−b=m(x−a)

Answers

Answer:

( y-b) / m    +a = x

Step-by-step explanation:

y−b=m(x−a)

Divide each side by m

(y−b)m=m/m(x−a)

( y-b)/m  = x-a

Add a to each side

( y-b) / m +a = x-a+a

( y-b) / m    +a = x

Answer:

y − b = m(x − a)

y − b = mx - ma

(y - b) / m = x - a

((y-b)/m) + a = x

The slope intercept form is y=mx+c, So y= -5/6x + 4 is in slope intercept form.

What is general equation of slope intercept form?

The general equation of slope intercept form is y=mx+c

where m is the slope and c is the y intercept

The given equation is y= -5/6x + 4, we have to check whether the given equation in slope intercept  form or not.

The given equation is y= -5/6x + 4...(1)

We know that general equation of slope intercept form is y=mx+c...(2)

As we compare equations (1) and (2), we find that equation (1) in the form of (2). so y= -5/6x + 4 is in slope intercept form.

Therefore y= -5/6x + 4 is in slope intercept form.

Water is poured into a container at a steady rate. After six minutes, 9.6 gallons of water are in the container. Let g represent the number of gallons of water in the
container after t minutes.
Select the equation that represents the relationship between g and t.
g= 0.6254
gt = 0.625
1.6g =1
g = 1.6t

Answers

Answer:

g = 1.6t

Step-by-step explanation:

Here, we want to select the equation that shows the correct relationship between g and t

We are told that after 6 seconds, we have 9.6 gallons of water

So the amount per second will be 9.6/6 = 1.6 gallons per second

So the relationship between the two will be

g = 1.6t

Where t is the time and g is the gallons
