Question

What would she have gotten for the equation of the linear function if she had used the ordered pairs (2, 5) and (4, 1) instead?

Answer 1

The answer is C

Explanation:

Answer 2

Answer: y = 2x + 9

Explanation:

slope(m) =
`\frac{y_(2)-y_(1)} {x_(2)-x_(1)}` =
`\frac{1-5} {4-2}` =
`(-4)/(2)` = -2

Point-Slope formula: y - y₁ = m(x - x₁)

y - 5 = -2(x - 2)

y - 5 = -2x + 4

y = 2x + 9
