Cada par de puntos determina una recta con la pendiente dada. Halla el valor de la incógnita en cada caso: a. (3,2);(4,x); m=1 b. (b,-1);(2,-2); m=-1/2 c. (5,d);(9,2); m=-3/4 d. (-1/3,3/4);(h,5/6); m=7/12

a=3,b=0,c=5,d=-4/21

Step-by-step explanation:

The formule we use to get the slope is:

m =

a. (3,2);(4,x); m=1

 → x= (1)(4-3)+2 → 3

b. (b,-1);(2,-2); m=-1/2

 → -1= ()(2-b) →   → 0

c. (5,d);(9,2); m=-3/4

 →  d= ()(9-5)-2 → 5

d. (-1/3,3/4);(h,5/6); m=7/12

  →  =   ()  →  

We get this equation with the original one:

y=mx+b

There are three  forms of linear equations:

point-slope form y2-y1=m(x2-x1)

standard form Ax + By + C = 0 or Ax + By = C

and slope-intercept form y=mx+b

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2

pls mark as brainliest

a is the right answer
