Find the equation of a line with a slope of -4 that passes through the point (-3, 8).

Nata [24]

Answer:

The equation of line is y = -4x -4.

Step-by-step explanation:

Given that:

Slope of the line = -4

Line passes through the point ( -3, 8)

The general equation of line is given by;

y - y1 =m(x-x1)

Putting the point and slope in equation

y - 8 = -4(x - (-3))

y - 8 = -4(x+3)

y - 8 = -4x - 12

y = -4x - 12 + 8

y = -4x -4

Hence,

The equation of line is y = -4x -4.

Oksana_A [137]

Answer:

1 and 1/8 hours or

Step-by-step explanation:

Natasha spent one and a half hours on the beach, which can be rewritten as 3/2 hours. Out of that time, she spent 3/4 sleeping. The total time she spent sleeping on the beach is determined by the product of the amount of time she spent on the beach by the fraction of that time she spent asleep:

$T=\frac{3}{2} * \frac{3}{4}\\T=\frac{9}{8} \\T=1 + \frac{1}{8}$
