Question

What is the equation of the line that passes through the points ( − 6 , − 1 ) and (0, 2)?

Answer 1

y=0.5x+2

Explanation:

y=mx+c

change in y over change in x

2+1/0+6 = 0.5

m=0.5

2=0.5×0+c

2=c

y=0.5x+2

Answer 2

y=1/2x+2

Explanation:

so slope = 2-(-1)/0-(-6)

=3/6=1/2

y=mx+b

plugging in the second group of cordinates.

2=1/2(0)+b

b=2

y=1/2x+2
