Question

Which of the following is the equation of the line in slope-intercept form that has a slope of -2 and

passes through the coordinate (4, 1)?
A) y = –2x - 7
B) y -1 = -2(x - 4)
C) y = -2x + 9
D) y = -2x

Answer 1

c). y = -2x + 9

Explanation:

y = -2x + b

1 = -2(4) + b

1 = -8 + b

9 = b
