Answer:

y = - 2x + 13

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 2, thus

y = - 2x + c ← is the partial equation

To find c substitute (7, - 1) into the partial equation

- 1 = - 14 + c ⇒ c = - 1 + 14 = 13

y = - 2x + 13 ← equation of line

The stopping distance d of an automobile is directly proportional to the square of its speed s.

IRINA_888 [86]

Answer:

192 feet is the stopping distance at 48 mph.

Step-by-step explanation:

Set up the proportion $\frac{x}{75} =\frac{48^{2} }{30^{2} }$

x/75 = 2304/900 cross multiply to get 900x = 172800

172800 ÷ 900 = 192

x = 192
