A person can walk 3 1/4 miles in one hour. How many miles can the person walk in 1 3/4 hours?

weqwewe [10]

Since Emily is walking at a constant speed, we can solve this using proportions, equating ratios of distance/time.

The first ratio is 3/4 miles/1/4 hour
The second ratio is 1 mile/ x hour

Equating the two ratios: 3/4 / 1/4 = 1/x
3 = 1/x
x = 1/3 hour

Slope -1 passes through (7,2)

kvv77 [185]

Y = mx + b
slope(m) = -1
(7,2)...x = 7 and y = 2
now we sub and find b, the y int
2 = -1(7) + b
2 = -7 + b
2 + 7 = b
9 = b

so ur equation of this line is : y = -1x + 9.....can also be written as :
y = -x + 9....or if u need it in standard form, it is : x + y = 9
