Step-by-step explanation:
7779.949783~7779.94978
Simply get the value of the angle and distribute away.
Answer:
use -4y for x in the second equation
-4 y + 5 y = 2
so
y = 2
then x = -4(2) = -8
(-8 , 2)
Step-by-step explanation:
Answer:
Equations in slope-intercept form for three different lines that intersect at (–2, 3) are y=-x+1 , y=3 and y=x+5
Step-by-step explanation:
General equation of slope intercept form : 
We are supposed to find equations in slope-intercept form for three different lines that intersect at (–2, 3).

Substitute the value in the general equation
y-3=m(x+2)
Now substitute any 3 values of m
At m = -1

At m =0

At m =1

They all intersect at the given point.
So, equations in slope-intercept form for three different lines that intersect at (–2, 3) are y=-x+1 , y=3 and y=x+5
