Question

How in the world do you put points into the standard form equation??

Answer 1

Equation for a line?
y = mx + b

point (x1,y1) is entered to make

y1 = m x1 + b to find b if not known already.

Answer 2

you have 3 formulas, slope intercept described by douglas: y =mx+b, where m= slope and b = y-intercept. ( where the line crosses the y axis and the value of the x axis is 0).
point slope: y-y1=m(x-x1). Where you will input your ordered pair or points ( x,y) in y1 and x1.
And standard form : ax + by = c.
