What is the point slope equation of the line through (3,6) (5,-8)

y-6 = -7(x-3)

Step-by-step explanation:

y - 6 = m(x - 3)

y-6 = -7(x-3)

y - 6 = -7(x - 3)

General Formulas and Concepts:

Pre-Algebra

Algebra I

Slope Formula:

Point-Slope Form: y - y₁ = m(x - x₁)  

Step-by-step explanation:

Step 1: Define

Point (3, 6)

Point (5, -8)

Step 2: Find slope m

Step 3: Write equation

Point (3, 6)

Slope m = -7

y - 6 = -7(x - 3)

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

50 min

step-by-step explanation:

they will be decreasing both their times in half

60 / 2 = 30

40/2 = 20

30 + 20 = 50
