Sphinxa [80]3 years ago

Answer:

  • 1) y = (-2/3)x +2/3
  • 2) y = (6/5)x -23/5
  • 5) y = (-1/6)x +4/3
  • 6) y = x -2

Step-by-step explanation:

A simple, mechanical way to do these (perpendicular lines) is ...

  • replace any constant with 0
  • swap the x- and y-coefficients, negating one
  • for point (h, k), replace x with (x-h) and y with (y-k)
  • solve for y (to get slope-intercept form)

1) 3x -2y = 0 . . . . . step 1

... 2x +3y = 0 . . . . step 2

... 2(x -1) +3(y -0) = 0 . . . . step 3

... 2x -2 = -3y . . . . eliminate parentheses, subtract 3y

... y = (-2/3)x +2/3 . . . . divide by the coefficient of y

2) 6(x -3) -5(y +1) = 0 . . . . after step 3

... 6x -23 = 5y . . . . . . . . . . simplify, add 5y

... y = (6/5)x - 23/5 . . . . . divide by the coefficient of y

5) (x+4) +6(y-2) = 0 . . . . . after step 3

... x -8 = -6y . . . . . . . . . . . simplify, subtract 6y

... y = (-1/6)x +4/3 . . . . . . divide by the coefficient of y

6) (y +5) = (x +3) . . . . . . . after step 3

... y = x -2 . . . . . . . . . . . . subtract 5

Find the equation of the line passing through (3,4), (-1,-2).
Kryger [21]

Answer:

(y-(-2))/(x-(-1)= (-2-4)/(-1-3)

(y+2)/(x+1)= (-6)/(-4)

(y+2)/(x+1)= (3/2)

Cross multiplying

2y+4= 3x+3

3x-2y-1=0

Liula [17]

Answer:

b. There's no statistically significant linear relationship between the number of miles driven and the maintenance cost

Step-by-step explanation:

The p-value for the slope estimate show us how strong is the certainty that there are a linear relationship between both variables. In this case, the p-value for the slopes shows if there is a significant relationship between the number of miles driven and the maintenance cost.

If we have a high p-value like 0.7 we can said that there is no certainty in the linear relationship. it means that there's no statistically significant linear relationship between the number of miles driven and the maintenance cost.
