Answer:

$\blue{b = \dfrac{2A}{h}}$

Step-by-step explanation:

$A = \dfrac{1}{2}bh$

Step 1. Switch sides.

$\dfrac{1}{2}bh = A$

Step 2. Since the fraction 1/2 multiplies b, multiply both sides by the reciprocal of 1/2 which is 2.

$2 \times \dfrac{1}{2}bh = 2 \times A$

$bh = 2A$

Step 3. Since h is multiplying b, and you want b alone, divide both sides by h.

$\dfrac{bh}{h} = \dfrac{2A}{h}$

Answer:

$b = \dfrac{2A}{h}$

The equation given is:

15x - 3y = 21

Slope intercept form is:

y = mx + b

15x - 3y = 21

-15x -15x

-------------------

-3y = -15x + 21

/-3 /-3 /-3

---------------------

y = 5x -7

The answer is: y = 5x - 7
