Respuesta :
The y-intercept of the line is represented by the -1 of the equation,
To get the equation in slope-intercept form: y = mx + b
y + 1 = x
Subtract 1 from both sides
y = x - 1
The y- intercept would be the b in the equation, so in this case it would have to equal -1 to make sense
STEP 1 )
Find y of the equation y +1 = x, then y = x-1, then for x = 0 , substitute it at the equation to find the y - intercept
step 2 )
y = 0-1, y= -1, this is the value of y - intercept
