Write an equation in point-slope form for the line that has a slope of
and contains the point (2, -9).



Where
y₁ = the y-coordinate of the point that the line contains
m = slope
x₁ = the x-coordinate of the point that the line contains
Provided Information:-
y₁ = -9
m = 
x₁ = 2
Substitute the values:-

On simplification,

According to the answer and explanation, we conclude that
[<u>The correct answer is Option B]</u>

U have a 2 term polynomial, also known as a binomial, with a degree of 5
5 skis and 8 skates
y=ski
x=skates
x=y+3
40y+50x=600
40y+50(y+3)=600
y=5
x=8
