(1.)find the slope of the line that passes through the given pair of points. (if an answer is undefined, enter undefined.) (? a + 3, b ? 3) and (a + 3, ? b) (2.)if the line passing through the points (a, 1) and (6, 5) is parallel to the line passing through the points (2, 7) and (a + 2, 1), what is the value of a?

1. The slope of the line is .

2. The value of a is 18.

Step-by-step explanation:

If a line passes through two points, then the slope of the line is

(1)

It is given that the line passes through the points (-a + 3, b - 3) and (a + 3, -b). So, the slope of the line is

The slope of the line is .

(2)

If the line passing through the points (a, 1) and (6, 5), then the slope of the line is

If the line passing through the points (2, 7) and (a + 2, 1), then the slope of the line is

The slopes of two parallel lines are same.

On cross multiplication we get

Divide both sides by -2.

Therefore the value of a is 18.

there are no figures how am i supposed to answer this question

step-by-step explanation:

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.
