Question

what is the equation of the line that passes through points (7,-4) and (-3,5)?

Answer 1

(y+4)/(-9)=(x-7)/(10)
10y+40=-9x+63
9x+10y=23

Answer 2

where do u get -9 from?

Answer 3

-4-5=-9

Answer 4

the rule is \[\frac{y-y_1}{y_1-y_2}=\frac{x-x_1}{x_1-x_2}\]

Answer 5

here (x1,y1)=(7,-4): (x2,y2)=(-3,5)
