Answer:

Y= 3X-7

Step-by-step explanation:

the equation of the line has the formular

Y-Y1= M (X-X1)

here, M= slope= 3

X1=2 Y1= -1

Y--1= 3(X-2)

Y+1= 3X-6

Y= 3X-6-1

Y= 3X-7

Answer:

y=3x-7

Step-by-step explanation:

<u>1. Use The Slope Formula</u>

y=mx+b

m=slope

b=y-intercept

<u>2. Fill in the given values</u>

y=3x+b

<u>3. Use the given points to solve for b</u>

-1=3*2+b

-1=6+b

-7=b

<u>4. Final equation</u>

y=3x-7

HELPPPPP ANSWER GETS BRAINLIEST

Answer:

56 degrees

Step-by-step explanation:

If you look at the m<KLN you can see that it is an acute angle. So, with this being said you have to know that the measure KLN is going to be less than 90 degrees. So you would subtract 180 and 124 and you would get 56 degrees.

I hope this helps :)
