<u>SOLUTION:</u>
General Equation: y = mx + b
.
Substitute slope = -2 into the equation:
y = -2x + b
.
Find the y-intercept:
4 = -2(-3) + b
4 = 6 + b
b = -2
.
Substitute b = -2 into the equation:
y = -2x - 2
.
Answer: y = -2x - 2
There is a total of 24 students in the class.
The probability of choosing a girl is 16/24. Which reduces down to 2/3 or 66%.
The probability of choosing a boy is 8/24. Which reduces to 1/3 or 33%.
So the student has a 66% chance of choosing a girl and 33% chance for a boy.
A=10 combine like terms which gives you a+2=12 then subtract two from both sides which gives you 10
