Write the equation For a Line that intersects points(1,3) And (2,5) which one is a.y=x+2 B.y=2x+1. C.y=3x-3. D.Y=-x+3 For me is letter B.please help

Answers

Answer 1

Answer: $(1,3) ,\ \ (2,5) \n \n \n First \ find \ the \ slope \ of \ the \ line \ thru \ the \ points \: \n \n m= (y_(2)-y_(1))/(x_(2)-x_(1) ) \n \nm=(5-3)/(2-1) = (2)/(1)=2 \n \nNow \ use \ y = mx + b \ with \ either \ point \ to \ find \ b, \ the \ y-intercept \ : \n \n y=mx+b \n \n3=2 \cdot 1+b\n \n3= 2 +b \n \nb=3-2=1 \n \n y=2x+1 \ is \ the \ answer \ B$

Answer 2

Answer: $3=a\cdot1+b\n 5=a\cdot2+b\n\n b=3-a\n 2a+b=5\n\n 2a+3-a=5\n a=2\n\n b=3-2\n b=1\n\n y=2x+1 \Rightarrow B$

Find the slope of the line through each pair of points (-7,13) (-15,-10)

Answers

Answer:

23/8

Step-by-step explanation:

Slope = Rise / Run

Rise = -10 - 13 = -23

Run = -15 - (-7) = -8

Slope = -23 / -8 = 23/8

In sunlight, a vertical stick 6 ft tall casts a shadow 2 ft long. At the same time a nearby tree casts a shadow 14 ft long. How tall is the tree? Round to the nearest tenth A) 42.0 ft 
B) 85.7 ft 
C) 18.0 ft 
D) 52.5 ft<br /

Answers

The nearby tree's height is 42.0 ft, which is A

Alrighty friend, let me explain you a math.
We're gonna want to start by setting up a fraction. We'll set up the fraction as height/shadow. The stick's height is 6 feet and the shadow is 2 feet, making the fraction 6/2. The second fraction only gives us the shadow, so the fraction is x/14.
Now, we're gonna do some cross multiplication m8. 6/2 x x/14. Multiply 6x14= 84 and 2x(x)= 2x ---> 2x = 84
Do you some basic algebra here, and divide both sides by 2.
Your final answer is 42, so the tree is 42 feet tall.
