Question

Given a line with slope of -1 and y-intercept of 8, which of the ordered pairs given below would NOT be on the line?

(2, 10)

(-1, 9)

(0, 8)

(3, 5)

Answer 1

(2,10) and (-1,9) would NOT be on the line

Explanation:

question is describing this linear equation:

y = -x + 8

(2,10) Does 10 = -2 + 8? NO

(-1,9) Does 9 = -1 + 8? NO

(0,8) Does 8 = 0 + 8? YES

(3,5) Does 5 = -3 + 8? YES

Answer 2

the point (2,10) would not be on the line because it's in the positive x direction.

Explanation:

y = -x + 8

10 = -2 + 8

10 + 2 = 8

2 = -10 + 8

2 = -2
