Option 1: y = -3x+3 is the right answer

Step-by-step explanation:

The slope-intercept form is given by:

y = mx+b

Here m is the slope and b is y-intercept

Given

m = -3

Point = (-1,6)

Putting the value of slope

y = -3x+b

To find the value of b, putting the given point (-1,6) in the equation

6 = -3(-1) +b\\6 = 3 + b\\b = 6-3\\b = 3

Putting the value of b in slope-intercept form

y = -3x+3

Hence,

Option 1: y = -3x+3 is the right answer

The taxi fare in a city is as follows: For the first kilometer, the
Ksju [112]

Answer:

The linear equation is y = 6 x + 9

The graph is attached down

Step-by-step explanation:

The given information:

The cost of 1st km is 9 Rs

The cost of every kilometer after the first is 6 Rs

x represents the number of km

y represents the total cost of x km

The form of the linear equation is

y = m x + b, where

  • m is the slope of the line (rate of change)
  • b is the y-intercept (initial value)

From the given information above

m = 6 Rs/km

b = 9 Rs

Substitute them in the form of the equation

y = 6 x + 9

The graph:

Andrei [34K]

Answer:

36 inches

Step-by-step explanation:

The ratio is L:W = 4:3 = 48:?

if you divide 48 by 4 you get 12. So now do 12 times 3 to get 36! Whatever you do to one ration do the same to the other, I like to remember it that way.
