Which equation represents the line that passes through points B and C on the graph?
Nataly_w [17]

Answer:

a

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

To calculate m use the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = B(- 4, 2) and (x₂, y₂ ) = C(- 2, - 2)

m = \frac{-2-2}{-2+4} = \frac{-4}{2} = - 2

y = - 2x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (- 2, - 2), then

- 2 = 4 + c ⇒ c = - 2 - 4 = - 6

y = - 2x - 6 ← equation of line through B and C

12% of birr x is 840,what is the value of x​
Diano4ka-milaya [45]

The value of x will be 7000 for the expression 12 % x = 840.

We are given a number x.

We are also given as 12 % of x is 840

writing it in the form of an expression, we get that:

12 % x = 840

12 / 100 × x = 840

12 x = 84,000

Dividing both sides by 12, we get that:

12 x / 12 = 84,000 / 12

x = 7000

Therefore, the value of x will be 7000.
