The formula for finding the area of an equilateral triangle is

square root of 3 * (a^2/2)

a is the side length so in this case is 6

square root of 3 * (18)

the area is about 15.6

Find the slope of a line that passes through the given points. Write your answer below.

12345 [234]

Just use the formula:
$slope(m) = \frac{y_2-y_1}{x_2-x_1}$

Then, plug in numbers:
$m = \frac{1-4}{-2-3} = \frac{-3}{-5} = \frac{3}{5}$

And that would be your answer: 3/5 is the slope.

Write the equation of a line passing through (0, 6) and parallel to the line y = 3/2x-7

Shkiper50 [21]

Parallel = same slope
Use formula: y = mx + b
Plug in the values (solve for b)
y = 3/2x + b
6 = 3/2(0) + b, b = 6

Solution: y = 3/2x + 6
