A line contains the point ( 3, 4). If the slope of the line is -2/3write the equation of the line using slope-intercept form.

7 0

You use point-slope form, which is y-y1=m(x-x1) , so it becomes
y-4=(-2/3)(x-3).
You can make it 3y-12=-2x+6.
Add 12 to both sides to make it 3y=-2x+18.
Lastly, divide everything by 3, so it becomes y=-2/3x+6.

Answer:

The answer to your question is 0.83 or 83%

Step-by-step explanation:

Data

5 red marbles

10 blue marbles

14 yellow marbles

Process

1.- Calculate the total amount of marbles

Total amount = 5 red + 10 blue + 14 yellow

Total amount = 29 marbles

2.- Calculate the amount of marbles that are not red

No red marbles = 10 + 14

= 24 marbles

3.- Calculate the probability

Probability of not pulling a red marble = $\frac{no red marble}{total amount of marbles}$

Probability of not pulling a red marble = $\frac{24}{29} = 0.83 or 83%$
