Answer:
The answer is 3
let me know if im wrong :)
<u>Let's solve this problem step-by-step</u>:
<u>First, let's set up the point-slope form</u>:
⇒ 
- (x₁,y₁) ==> point on the line
- m ==> value of slope of the line
<u>Let's examine what we are given:</u>
- (-2,9) ==> point on the line
- -8 ==> slope of the line
<u>Let's plug in all the known values in the point-slope form</u>:

<u>To convert from point-slope form to slope-intercept form</u>:
⇒ must solve for 'y'
⇒ (<em>in other words</em>) must isolate y to one side and everything else to
the other side
<u>Let's solve</u>:

<u>Answer: y= -8x - 7</u>
Hope that helps!
Answer: im not sure sorry
Step-by-step explanation:
3a - 4b = 21
check (-2 , -3)
3(-2) -4(-3) =21
-6 +12 = 21
6 does not = 21 so NO
check (0 , 7)
3(0) -4(7) =21
0-28=21
-28 does not equal 21 so NO
check (-3 , -2)
3(-3) -4(-2) =21
-9 +8 = 21
1 does not = 21 so NO
check (7 , 0)
3(7) -4(0) =21
21 = 21
Choice D
Answer:
The answer is 7
Step-by-step explanation:
I don't know how to explain it really but just divide 4/3 by 28/3 and you should get the answer of x
