Y=mx+b
(x,y)
m= slope
b= y-intercept
slope is y2-y1/x2-x1
find your slope and then put a coordinate pair in your equation (y=mx+b) then solve to get a number for b.
Try it using the coordinates
 (66,64) and (68,66)
  x1  y1           x2  y2

Try it and put your answer in the comments and I will tell you if you are right!

The answer is 3. If you set it up in a T table and label x as the number of hours and y as the number of rows. Then use rise over run (y over x) the fractions simplify to 3 over 1.

19x+rx= -37x+w what is the x
seraphim [82]

Answer:

x = w / (56 + r)

Step-by-step explanation:

Given the equation :

19x + rx= -37x + w ; find x

Collecting like terms

19x + rx + 37x = w

Factorizing x in the Left hand side

x(19 + 37 + r) = w

x(56 + r) = w

Therefore we can obtain x by dividing both sides by (56 + r)

x(56 + r) / (56 + r) = w / (56 + r)

x = w / (56 + r)

  • Third- put the number 4.75 out to the left of the decimal box
  • Fourth- when that's all completed you have to multiply the 475. until you get clos to the number 2140.
  • Fifth- once done you have to subtract the multiplied number that you get you then subtract it from 2140
  • Sixth- you keep on doing the fifth step until you get a reasonable answer
  • Seventh- you write the answer down
