find the equation of a line that passes through (-3,1) and (-1,-2) and write it in standard form. please help me !

Savatey [412]

Find the slope first
slope=(2-1)/(-1+3)=1/4=.25

now use the slope and either point to write in point slope form
y-1=.25(x-2)
y-1=¼x-½

to rationalize all the denominators multiply by the last common multiple, here we get 4
4y-4=x-2

then put in the correct order

x-4y=-2

HI could some please help me out , I will give BRAINLEST

The answer is y = -1/3x + 2

Because the y intersect is located at (0,2) we know that the b value in the formula y=mx + b is 2 and using rise over run we determine the slope to be -1/3

Answer:

y=57 degrees and x=66 degrees

Step-by-step explanation:

123+57 =180 so angle y=57 degrees

57+57=114 all triangles = 180 degrees so 180-114=66 degrees=X

125 tickets were sold for the jazz band concert for a total of $1,022. Students tickets cost $6 each, and general admission tick

rodikova [14]

Answer:

Number of student tickets sold are 57 and general tickets sold are 68.

Step-by-step explanation:

Let the number of student tickets = x and the number of general tickets = y.

It is given that in total 125 tickets were sold.

So, we have,

$x+y=125$

Also, students tickets is sold for $6 each and the general tickets are sold for $10 each.

Since, the total cost of the tickets is $1022.

So, we get,

$6x+10y=1022$

Thus, the system of equations obtained is,

x + y = 125 ........................(1)

6x + 10y = 1022

Multiply equation (1) by 6 gives us,

6x + 6y = 750 ............................(2)

6x + 10y = 1022 .........................(3)

Subtact (2) from (3), we get,

10y - 6y = 1022 - 750

i.e. 4y = 272

i.e. y= 68.

So, equation (1) gives,

x = 125 - y

i.e. y = 125 - 68

i.e. y = 57

Hence, the number of student tickets sold are 57 and general tickets sold are 68.
