Aline passes through (9, –9) and (10, –5).write an equation for the line in point-slope form.
rewrite the equation in standard form using integers.
a) y + 9 = 4(x + 9) ; -4x + y = -45
b) y - 9 = 4(x + 9) ; -4x + y = 45
c) y - 9 = 4(x + 9) ; -4x + y = -45
d) y + 9 = 4(x + 9) ; -4x + y = 45
^^ the options look pretty similar, so make sure you're answering correctly! you : )
