I believe the answer is B: 13.2 because to find the area of a triangle you do l x w x 1/2.

8 x 3.3 x 1/2 = 13.2.

Complete the point slope equation of the line through (-5, 7) and (-4, 0).

IgorLugansk [536]

For this case we have that by definition, the point-slope equation of a line is given by:

$y = mx + b$

Where:

m: It's the slope

b: It is the cut-off point with the y axis

We have two points:

$(x_ {1}, y_ {1}): (- 5,7)\\(x_ {2}, y_ {2}): (- 4,0)$

We found the slope:

$m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}} = \frac {0-7} {- 4 - (- 5)} = \frac {-7} {-4 + 5} = \frac {-7} {1} = - 7$

Thus, the equation is of the form:

$y = -7x + b$

We substitute one of the points and find "b":

$0 = -7 (-4) + b\\0 = 28 + b\\b = -28$

Finally, the equation is:

$y = -7x-28$

Answer:

$y = -7x-28$

Question 2 Answer Solve

Lelu [443]

Answer:

Option B is correct.

Step-by-step explanation:

To subtract fractions, we must check if the denominators of both fractions are the same.

2/5 - 1/7
=> 2 x 7/5 x 7 - 1 x 5/7 x 5
=> 14/35 - 5/35

Now, let's subtract for the result.

=> 9/35

Hence, Option B is correct.

Hoped this helped.
