Find the equation of line passing through points a (1, 3) and b (3, 7).

Solution:

To find the equation of line passing through points A (1, 3) and B (3, 7).

we know that, to derive the equation of a line we first need to calculate the slope of the line. Slope m of a line at points and is given by - .

Slope of the line at point A(1,3) and B(3,7)

Equation of a line using a point and a slope ,

The equation of line passing through points A (1, 3) and B (3, 7) :

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

step-by-step explanation: the answer is 27. first multiply .32 by 25 which equals 8. then add 8 to 25 which gives you 33. then you subtract that from 6 since she gave 6 to her brother.
