Question

What is the slope-intercept form of the function that contains the point (6, 2) and has a slope of 3?
y=___x+___

Answer 1

Point-slope form is y-y1=m(x-x1). Plug in the given values.
y-2=3(x-6)
Distribute.
y-2=3x-18
Add 2 to both sides.
y=3x-16

Answer 2

Thats what i got but i was confused because when i enter the problem its a (+) and not (-)

Answer 3

I see. Remember that y=3x-16 can also be written as y=3x+(-16).
