Which of the following point-slope form equations could be produced with the points (6, 1) and (3, -2)? a. y - 1 = -1(x - 6) b. y + 1 = 1(x - 6) c. y + 1 = 1(x + 6) dx. y - 1 = 1(x - 6)

Its d

Step-by-step explanation:

The slope  is (-2-1) / (3 - 6) =  -3/-3 = 1

and as one point on the line is (6, 1) the equation is

y - 1 = 1(x - 6)

let soccer = x and golf = y

part a

1st equation: x + y = 125

2nd equation: x = y +45

part b

replace x in the 1st equation with the 2nd one:

y + 45 + y = 125

simplify:

2y + 45 = 125

subtract 45 from each side:

2y = 80

divide both sides by 2:

y = 80/2

y = 40

she plays golf for 40 minutes.

part c

no because she plays soccer for 45 minutes longer than golf 40 +45 =   85 minutes, not 80 minutes.
