What is the equation of the following line? (0,0) (6,2)
leva [86]

If you want it to be a slope intercept form, the first you have to find slope.

y2-y1/x2-x1

2-0/6-0

2/6 = 1/3

Then you need to find the y intercept. Plug in the x and y value in y=mx+b.

2=1/3(6)+b

2=2+b

0=b

ANSWER: y=1/3x+0

Hope this helps and is correct :)

PLEASE SOLVE
kherson [118]

Answer:

14/5

Step-by-step explanation:

So first i manipulated a/b= 2/5. i multiplied both sides by 5 making it 5a/b=2. Then i multiplied both sides by b making it 5a=2b. Then i substituted 2b into 5a+3b=35. Making it 2b+3b=35. then i simplified it making it 5b=35. Then i solved for b making it b=7. Then i substituted b into 5a+3b=35. So that it looked like this 5a+3*7=35. then it became 5a+21=35. Then you subtract 21 making it 5a=14. You then divide by 5 making it a=14/5

Please solve this<br> Find H.C.F <br>m^3 - 1, m^4 + m^2 + 1, m^2+ m + 1​
adelina 88 [10]

Answer:

m^2+m+1

Step-by-step explanation:

  • m^3 - 1= (m-1)(m^2+m+1)
  • m^4 + m^2 + 1= m^4+2m^2+1 - m^2= (m^2+1)^2 -m^2= (m^2+m+1)(m^2-m+1)
  • m^2+ m + 1​

HCF= m^2+m+1 which is the factor of all three polynomials
