Write an equation in standard form of the line that passes through (3, 1) and has a y intercept of -2

aleksandr82 [10.1K]

Step-by-step explanation:

First of all, use substitution to find slope

(1) = m(3) - 2

3 = m3

m = 1

With both the slope and y int, you can write it in y int form

y = 1x - 2

Convert that to standard form

-x + y = -2

In triangle JKL, angle K is a right angle. Write the sine of angle J as a ratio of side lengths

Evgen [1.6K]

Answer:

$Sin J =\frac{|KL|}{|JL|}$

Step-by-step explanation:

In Right Triangle JKL, with Right angle at K

$sin \theta =\frac{Opposite}{Hypotenuse} \\$

Opposite =|KL|

Hypotenuse=|JL|

Therefore, sin J as a ratio of side lengths is:

$Sin J =\frac{|KL|}{|JL|}$
