Taya2010 [7]

Answer:

The equation of the sraight line 3x- y+ 6 =0

Step-by-step explanation:

Explanation:-

Given that the gradient of the function

|gradf| = 3 and point (-1,3)

Given that the slope of the line

m = 3

The equation of the straight line passing through the point(-1,3) and slope m =3

$y -y_{1} = m(x-x_{1} )$

y-3 = 3(x-(-1))

y-3 = 3x+3

3x +3-y+3=0

3x- y+ 6 =0

Final answer:-

The equation of the sraight line 3x- y+ 6 =0

77julia77 [94]

Answer:

3 31/36 inches

Step-by-step explanation:

11 1/9 = 100/9

7 1/4 = 29/4

100/9 = 400/36

29/4 = 261/36

400/36 - 261/36 = 139/36

139/36 = 3 31/36
