Write an equation in point slope form of a line that passes through the given point and has the given slope.
maxonik [38]

the equation of a line in point-slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

here m = - 2 and (a, b) = (2, 6), hence

y - 6 = - 2(x - 2) ← equation in point-slope form

Greeley [361]

Answer:

12\dfrac{1}{8}\ feet

Step-by-step explanation:

Sonya drops a marble while standing on a deck 7 \dfrac{7}{8} feet above the ground.

The marble falls 4 \dfrac{1}{4} feet from Sonya's hand to the deck, and then rolls and falls to the ground.

So, the ball falls 4 \dfrac{1}{4} feet from Sonya's hand to the deck  and 7 \dfrac{7}{8} from the deck to the ground, in total

4\dfrac{1}{4}+7\dfrac{7}{8}=4\dfrac{2}{8}+7\dfrac{7}{8}=(4+7)+\dfrac{2+7}{8}=11+\dfrac{9}{8}=11+1\dfrac{1}{8}=12\dfrac{1}{8}\ feet
