Question

Graph by finding points y= -1/2x-1 use x=-2,0,2

Answer 1

Explanation:

y = -1/2x - 1 and x = -2,0,2

y1 = [- 1/2*(-2) ] -1 = [(-1)/(-4) ]-1 = 0 ,25 -1 = -0,75

when you have :

(-) / (-) = (+)

(-) / (+) = (-)

(-) + (-) = (-)

if x = 0 (can't divide by zero )

if x = 0,2

y2= [- 1/2*(0,2) ] -1 = [(-1)/(0,4) ]-1 = - 2,5 -1 = - 3,5

so for your graph you will have :

x1 = -2

x2 = 0,2

y1 = - 0,75

y2= -3,5
