The first one, The square root is a factor of a number. :D
I'm pretty sure it's 9÷12.
y-y1=m(x-x1) where m is the slope, and (x1,y1) can be either one of the two points you are given. First, we need to find the slope m from the given points. Now put the point (2,3) in the point-slope equation along with the slope m to find the equation of the line between the two points.
Answer: x=2−2√3,2+2√3
Step-by-step explanation:
