Answer 1

Answer: y=(1/2)x-1

Solution:

Slope-intercept form: y=mx+b

Intercept with y-axis: P1=(0,-1)=(0,b)→b=-1

Slope: m=(y2-y1)/x2-x1)

P1=(0,-1)=(x1,y1)→x1=0, y1=-1

P2=(2,0)=(x2,y2)→x2=2, y2=0

m=(0-(-1))/(2-0)

m=(0+1)/2

m=1/2

Replacing in the slope intercept form:

y=mx+b

y=(1/2)x+(-1)

y=(1/2)x-1
