Describe the procedure you
performed to derive the slope-intercept form of a linear equation.

Answers

Answer 1

Answer:

Answer:

1. You first have to find the slope

2. Next, you have to find the y-intercept

3. Finally, you have to put it in y = mx + b form.

Step-by-step explanation:

The slope of 2 points is; $(y_(2)- y_(1) )/(x_(2)-x_(1))$

The y-intercept is; $y-y_(1)=m(x-x_(1) )$

y = mx + b

m is always the slope

b is always the starting point or y-intercept

Answer 2

Answer:

Answer:y=mx+b

Step-by-step explanation:

To summarize how to write a linear equation using the slope-interception form you

Identify the slope, m. This can be done by calculating the slope between two known points of the line using the slope formula.

Find the y-intercept. This can be done by substituting the slope and the coordinates of a point (x, y) on the line in the slope-intercept formula and then solve for b.

Once you've got both m and b you can just put them in the equation at their respective position.

1 times something is the same number

so

$(6)/( (3)/(4) )$

make bottom 1
3/4 times 4/3=12/12=1 so

times wole thing by
$((4)/(3))/( (4)/(3) )$

result
$((6)((4)/(3)))/(((3)/(4))((4)/(3)) )$ =
$((24)/(3))/((12)/(12) )$ =
$(8)/(1 )$ =8

Answer:

Cone is equal to 3, white ice cream is equal to 2, and the pink is equal to 1.

Step-by-step explanation:

Something times something times something is equal to 27, and 27=3x is equal to 3. The cone is equal to 3.

3+3=6, and since 10-6 =4, 4=2x, so the white ice cream is equal to 2.

3+3+3=9, and 2+2=4, 9+4=13, so 15-13=2, and 2=2x, so the pink ice cream is equal to 1.

the measure of one angle is eleven more than four times a number another angle is twice the first angles measure the sum of the measures of the angles are 195 degrees what is the measure of each angle

Answers

Answer=65° & 130°

195°=angle1+angle2
195°=(11+4x)+2(11+4x)
195°=33+12x
subtract 33 for both sides
162=12x
13.5=x

Now lets solve for the measure of the angles

angle1=11+4x
angle1=11+4(13.5)
angle1=11+54
angle1=65°

angle2=2(11+4x)
angle2=2(11+4(33.5))
angle2=2(11+54)
angle2=2(65)
angle2=130°

x, y, and z are the angles
so
x is 11 more than 4 times y
x=11+4y

z is twice the first angles measure
z=2x

the sum of the angles is 195
x+y+z=195

so we have
x=11+4y
z=2x
and
x+y+z=195
make everything y
subsitute 11+4y for x
11+4y+y+z=195
subsitute 2x for z
11+4y+y+2x=195
subsitute 11+4y for x
11+4y+y+2(11+4y)=195
distribute
11+4y+y+22+8y=195
group according to type
(4y+y+8y)+(11+22)=195
add like terms
13y+33=195
subtract 33 from both sides
13y=162
divide both sides by 13
y=12 and 8/13
subsitute
x=11+4y
x=11+4(12 and 6/13)
x=11+48 and 24/13
x=11+49 and 11/13
x=60 and 11/13
z=2x
z=2(60 and 11/13)
z=120 and 22/13
z=121 and 9/13

the angles are
12 and 6/13
60 and 11/13
121 and 9/13 or aprox

What is the equation of the line that passes through (5;-2) and (-3;4

Answers

Step-by-step explanation:

Given points are: $(5, - 2) =(x_1,\:y_1) \:\&\: (-3, 4)=(x_2,\:y_2)$

Equation of line in two point form is given as:

$(y -y_1 )/(y_1 - y_2) = (x -x_1 )/(x_1 - x_2) \n \n \therefore \: (y -( -2 ) )/( - 2 - 4) = (x -5 )/(5 - ( - 3)) \n \n\therefore \: (y + 2 )/( - 6) = (x -5 )/(5 + 3) \n \n\therefore \: (y + 2 )/( - 6) = (x -5 )/(8) \n \n\therefore \: (y + 2 )/( - 3) = (x -5 )/(4) \n \n\therefore \: 4(y + 2 ) = - 3(x - 5) \n \n \therefore \: 4y + 8 = - 3x + 15 \n \n \therefore \: 3x + 4y + 8 - 15 = 0 \n \n \huge \: \orange{ \boxed{\therefore \: 3x + 4y - 7 = 0}} \n \: \: is \: the \: required \: equation \: of \: line$
