-12
Which system of equations is represented by lines m and n?
a. 3x - y = 6
4x + 9y = 4
b. 3x - y = 2
4x + 9y = 36
C. x-3y = -18
9x + 4y = 9
d. x + y = 10
9x + 4y = 13

B

Step-by-step explanation:

slope formula

we have the two points

(2,4) (3,7)

which means the slope for line m is 3x

our equation so far looks like this

y=3x+b

plug in a set of numbers to solve for b

let's use (2,4)

4=3(2)+b

4=6+b

b= -2

which means our equation is

y= 3x-2

which is equal to

2= 3x-y

the only answer is then B

answer: a and c are correct

step-by-step explanation:

the +5 is the vertical translation

the added negative symbol in front is the reflection over the y-axis

answer: 230 miles ( vote ! )

step-by-step explanation:

180.39 minus 17.99 equals 162.4

then divide 162.4 by .80 to get 230
