Question

Graph the equation and identify the y-intercept. y + x= -5. Please help

Answer 1

let y = 0

can you solve for x in your head by just looking at the resulting equation?

Answer 2

x + y = -5
y-int: Let x = 0 and solve for y:
0 + y = -5
y = -5. P1(0 , -5).

x-int: Let y = 0 and solve for x:
x + o = -5
x = -5. P3(-5 , 0).

Graph: P1(0 , -5) , P2(-3 , -2) ,
P3(-5 , 0).
