Question

Please please help me with this

Answer 1

y - 1 = - (x - 2)

Explanation:

The equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (2, 1) and (x₂, y₂ ) = (- 2, 5)

m =
`(5-1)/(-2-2)` =
`(4)/(-4)` = - 1

Using (a, b) = (2, 1), then

y - 1 = - 1(x - 2), that is

y - 1 = - (x - 2)
