Answer:
Option (4)
Step-by-step explanation:
In the picture attached,
m∠NLM = m∠LKN = 90°
In two similar triangles ΔLKN and ΔMKL,
By the property of similar triangles,
"Ratio of the corresponding sides of the similar triangles are proportional".
By substituting the values given,
Therefore, Option (4) will be the answer.
Answer:
y + 1 = (x + 2)
Step-by-step explanation:
The equation of a line in point- slope form is
y - y₁ = m(x - x₁)
where m is the slope and (x₁, y₁ ) a point on the line
Calculate m using the slope formula
m =
with (x₁, y₁ ) =(- 2, - 1) and (x₂, y₂ ) = (2, 1) ← 2 points on the line
m = =
=
with point on line (x₁, y₁ ) = (- 2, - 1 ), then
y - (- 1) = (x - (- 2) ), that is
y + 1 = (x + 2) ← equation of line
