What is the point-slope form of a line with slope 3 that contains the point (2, 1)?

a. y - 1 = 3(x - 2)
b. y - 2 = 3(x + 1)
c. y - 2 = 3(x - 1)
d. y + 1 = 3(x + 2)

Equation A.y - 1 = 3(x - 2).

Step-by-step explanation:

Given :  A line with slope 3 that contains the point (2, 1).

To find : What is the point-slope form of a line .

Solution : We have given that

slope = 3

Point  (2, 1).

By the point-slope formula: which states that given a point and a slope m, the equation of the line can be written as y - = m(x - ).

Here = ( 2, 1)

m = slope = 3 .

Then Equation of line  y - = 3(x - ).

Therefore, Equation A.y - 1 = 3(x - 2).

explanation:

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
