What equation represents the road that passes through the point shown and is perpendicular to the road represented by the red line?

y = -1/3 x + 1/3

Step-by-step explanation:

The red line passes through points (0, 2) and (2, 8).

The slope of the red line is (8 - 2)/(2 - 0) = 6/2 = 3

The slope of the perpendicular line is -1/3, and it passes through point (1, 0).

y = mx + b

y = -1/3 x + b

0 = (-1/3)(1) + b

b = 1/3

y = -1/3 x + 1/3

add all the numbers and check the ones place.

the answer is 486. as the ones place is more than 4, the estimation will be the next 10 ie, 490

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
