1. Find Slope
m = y2-y1/x2-x1
m = -6 - 5/2-4
m = -11/-2
m = 11/2
2. Write equation with know information
y = mx + b
y = 11/2x + b
3. Choose any of the two points (doesn’t matter which in you choose) and replace the x and y value into the equation
y = 11/2x + b (4,5)
5 = 11/2(4) + b
5 = 22 + b
Use algebra and solve for b
5 - 22 = b
b = -17
State all the information you know
m = 11/2 b = -17
Write the equation
y = 11/2x - 17
W -width of the brand name TV, L - length of the brand name TV;
3/8 W = 12
W = 12 : 3/8 = 12 · 8/3 = 32 in
3/8 L = 24
L = 24 : 3/8 = 12 · 8/3 = 64 in
Answer: A ) 32 inches by 64 inches.
X^3+3x^2-18x-3x^2-9x+54

Final answer=
X^3-27x+54
I hope you understand my explanation and best of wishes!!
x^2 - 49 = 0
Add 49 to both sides:
x^2 = 49
Take the square root of both sides:
X = 7
