What is the y-intercept?<br> y-3=1\2(x+2)
Margaret [11]
Y-3=1/2(x+2)

To find the y-intercept, we must first get the equation in slope intercept form. Start off by distributing 1/2 into the parentheses.

y-3= 1/2x+1
Add 3 to both sides

y= 1/2x+4

The slope is whatever is in front of x, in this case, 1/2. The y-intercept is the number after that which would be 4

In triangle JKL, m of angle J = 90, m of angle K = 30, and m of angle L = 60. Which of the following statements about triangle J
Lynna [10]

Answer:

option C. KL=2*JL

option D. JK=\frac{\sqrt{3}}{2}*KL

option F. JK=\sqrt{3}*JL

Step-by-step explanation:

step 1

we know that

In the right triangle JKL

sin(30\°)=\frac{JL}{KL}

sin(30\°)=\frac{1}{2}

so

\frac{1}{2}=\frac{JL}{KL}

KL=2*JL

step 2

cos(30\°)=\frac{JK}{KL}

cos(30\°)=\frac{\sqrt{3}}{2}

so

\frac{\sqrt{3}}{2}=\frac{JK}{KL}

JK=\frac{\sqrt{3}}{2}*KL

step 3

tan(30\°)=\frac{JL}{JK}

tan(30\°)=\frac{1}{\sqrt{3}}

\frac{1}{\sqrt{3}}=\frac{JL}{JK}

JK=\sqrt{3}*JL
