The points (0, 1) and (-9, -9) fall on a particular line. What is its equation in slope-intercept form?
prohojiy [21]

The slope-intercept form:

y=mx+b\\\\m=\dfrac{y_2-y_1}{x_2-x_1}

m - slope

b - y-intercept → (0, b)

We have the points (-9, -9) and (0, 1) - y-intercept → b = 1.

Calculate the slope:

m=\dfrac{1-(-9)}{0-(-9)}=\dfrac{10}{9}

Answer: y=\dfrac{10}{9}x+1

What is -5/6 + -5/6? (its ment to be a fraction)
maks197457 [2]
The answer is:  " -5/3 " ;  or, write as:  " -1 ⅔ " .
_____________________________________________
Explanation:
_____________________________________________

   (-5/6) + (-5/6) = (-5/6) <span>− (5/6) ;  

------>  {since: "adding a negative" is the same a "subtracting a positive"} ; 

------> </span> (-5/6) − (5/6) = (-5 − 5) / 6  ;
  
                                  =   -10/6 =  (-10/2) / (6/2) ;
_____________________________________________________
                                  =   " -5/3 " ;  or, write as:  " -1 ⅔ " .

If the map ratio of a map is 1:100000 and the distance between two
dsp73

Answer:

Given that,

Map scale = 1:100000

Map distance = 8cm

Therefore,

MD ÷ AD = 1 ÷ 100000

8 ÷ AD = 1 ÷ 100000

AD = 8 × 100000

AD = 800000
