Question

Referring to the figure, what is the slope of the
line? pls quick

Answer 1

26) 70

27) 12.86 sec

28) 350 feet

Explanation:

26) Given points A(0, 0) and B(16, 1120)

slope m =
`(y_2-y_1)/(x_2-x_1)`

`=(1120-0)/(16-0)\\ \\=(1120)/(16)\\ \\=70`

slope = 70

27) eq of a line is :

y = mx + c

y = 70x + c

Since the line passes through A(0,0) substituting the points in the equation,

0 = 70(0) + c

⇒ c = 0

eq of line: y = 70x

given distance is 900 ft

y = distance and x = time

⇒ y = 900

sun in eq,

900 = 70x

⇒ x = 900/70

⇒ x = 12.86

28) time is 5 sec

⇒ x = 5

sub in eq

y = 70(5)

⇒ y = 350
