Question

What is the equation of a line that has a slope of 2 and passes through the point (1,-9)?

Answer 1

I’m not sure what kind of equation you want but if you want point slope it’s
Y+9=2(x-1) because the formula is y-y1=m(x-x1) so you just fill it in but if this isn’t the kind of answer you were looking for I wouldn’t mind helping you in the comments :)
