Find the slope of the line through each pair of points (15,8) and (-17,9)
PtichkaEL [24]

Answer:

-1/32

Step-by-step explanation:

Find the slope using rise over run, (y2 - y1) / (x2 - x1)

Plug in the points, and simplify:

(y2 - y1) / (x2 - x1)

(9 - 8) / (-17 - 15)

1 / -32

= -1/32

So, the slope of the line is -1/32

A car is traveling at a speed of 55 mph. You want to write an algebraic expression to show how far the car will travel in a cert
WARRIOR [948]

distance = rate * time.

distance is number of miles the car has traveled.

rate = number of miles per hour the car is traveling at.

time = number of hours the car has been driven.

let D = distance.

let T = time.

let R = rate


the general equation is D = R*T

as long as the car will always be driven at 55 miles per hour, you can substitute 55 for R and that becomes your constant.

The equation then becomes D = 55 * T.

example:

you drive 5 hours.

D = 55 * T = 55 * 5 = 275 miles.

If you drive at 55 miles per hour for 5 hours, you will have driven 275 miles.

Hope this helps!
