You can use point-slope form to find the equation of a line if you know any two points the line passes through and find the line's slope. For example, let's find the equation of the line passing through points (−1, 1) and (1, 2).

Respuesta :

y=1/2x+1.5 is the equation

Answer:

y=1/2x+1/5

Step-by-step explanation:

2-1=m(1+1)

1=m(2)

1/2=m

Plug it into your y=mx+b

y=1/2x+b

Find b by plugging one of your ordered pairs in

2=1/2(1)+b

2=1/2+b

1.5=b

Plug it into your original expression

y=1/2x+1.5
