Find the equation of the line with slope=6 and passing through (8,51). Write your equation in the form y=mx+b.
zzz [600]

Answer:

The answer to your question is: y = 6x + 3

Step-by-step explanation:

Data

slope = m = 6

A (8, 51)

Equation

                 y = mx + b

               (y - y1) = m (x - x1)

               (y - 51) = 6(x - 8)

               y - 51 = 6x - 48

                     y = 6x - 48 + 51

                     y = 6x + 3

The area of a rectangular garden is 3927cm . If the width of the garden is 51 m , what is its length?
Galina-37 [17]

Answer:

77

Step-by-step explanation:

The area of a rectangle is A = lw. 'A', the area, is 3927, and 'w', the width, is 51. By substituting the values in, we get that 3927 = 51L. Dividing both sides by 51, we get that L, the length, is 77.
