Question

A line with a slope of 1/2 passes through the point (2,-1). What is the equation of this line ?

Answer 1

I believe the equation would be y=mx+b, m being slope, b being y-intercept, so it would mean that you need to plug in the numbers. I believe the final equation would be y=1/2x+(-1)

Answer 2

equation of a line tha passes through thte point (x1,y1) and has a lsope of m is
y-y1=m(x-x1)

given
m=1/2
point is (2,-1)
x1=2
y1=-1

y-(-1)=1/2(x-2)
y+1=1/2(x-2)
if yo want slope intercept
y+1=1/2x-1
y=(1/2)x-2
