Find the x-intercept of 2x - y = -6. im so confused please help me

-3

Step-by-step explanation:

First, you need to put it in slope intercept form, which is y=2x+6. To find the x int., plug in y for 0. Get x by itself to get -6=2x. Then solve for x to get -3.

TL;DR

-y=-2x-6

y=2x+6

0=2x+6

-6=2x

-3=x

i just took the test, the correct answer is .. 31.5 in.

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
