What is the formula for the slope of a line passing through two points?

• Y = x2-x1 / y2-y1

• Y = y2-y1 / x2-x1

• Y = x2+x1 / y2+y1

• Y = y1+y2 / x1 + x2

Why would a line have an equation that looks like this:

y = kx

instead of this:

y = mx + b ?

• Someone doesn't like the letter 'm'.

• The first equation is a line that is horizontal

• The first equation is a line that is vertical

• The first equation is for a line that crosses the y-intercept at zero.

Mac, our mathematical poogle, wants to know:

What is the slope of a vertical line?

He says that vertical is like how he is sitting rn, up and down,

NOT when he lays down flat on his rock. :)

• slope = 0

• Slope = 1

• Undefined

• Slope = -1
