Find point-slope.(3/2, -1/2)
(-2/3, 1/3)

x1: 3/2
x2: -2/3
y1: -1/2
y2: 1/3

to find slope:
m= y2-y1/x2-x1

point-slope:
y-y1=m(x-x1)

Answers

Answer 1

Answer: this iis easie guise, why don't you do it? so
point slope=y-y1=m(x-x1)

so just subsitute
first find m
m=(y2-y1)/(x2-x1)=(1/3-(-1/2))/(-2/3-3/2)=(1/3+1/2)/(-2/3-3/2)=(5/6)/(-13/6)=-5/13
m=-5/13
subsitute
y-y1=-5/13(x-x1)
subsitute
y-(-1/2)=-5/13(x-3/2)
y+1/2=-5/13x+15/26
subtract 1/2 from both sides
y=-5/13x+15/26-13/26 (1/2=13/26)
y=-5/13x+2/26
y=-5/13x+1/13

Answer 2

Answer:

Answer:

Step-by-step explanation:

Sample Answer:When a linear function is expressed in different forms, its slope and y-intercept remain the same. The slope from the equation is -1, and the y-intercept from the equation is 3. The slope from the table is -1, and the y-intercept from the table is −3. These are not the same functions.

hope this helps.

The cost of a taxi ride is 5 dollars plus 50 cents per mile. write an algebraic expression that models the cost of a taxi ride of m miles. A. m(5+0.5)
B.5+ 0.5/m
C.5+0.5m
D.5m+0.5

Answers

Answer:

Option C. 5 + 0.5m

Step-by-step explanation:

The cost of a taxi ride is = $5.00

with per mile charges = 50 cents = 0.5 dollar

If the taxi ride of m miles, to find the cost of a taxi ride, the expression will be

$5 + m($0.5)

Therefore Option C., 5 + 0.5m is the correct answer.

Simple.....

you have 5 dollars that it costs PLUS 0.50 PER mile.

Writing your equation...

0.5m (m=per mile extra)

5(how much it initially costs)

0.5m+5

Thus, your answer, C.

The question that I'm having issues with is, "The complement of an angle, A, in degrees, is equal to one-sixth of the supplement of the angle, also in degrees. Then A= "I know the answer is 72 degrees, but I don't know how to figure the problem out!

Answers

'Complement' = difference between an angle an 90 degrees.

'Supplement' = difference between an angle and 180 degrees.

Complement of A = 90 - A

Supplement of A = 180 - A

The problem says that the complement is 1/6 of the supplement, right ?

So 90 - A = (1/6) x (180 - A)

Multiply each side of this equation by 6 :

540 - 6 A = 180 - A

Subtract 180 from each side:

360 - 6 A = - A

Add 6A to each side :

360 = 5 A

Divide each side by 5 :

A = 72°

$90-A=(180-A)/(6)\n 540-6A=180-A\n 5A=360\n A=72$
