Question

equation of a line passing through (-3,7) and (7,-8)

Answer 1

y - y1 = (y2-y1)/(x2-x1) * (x-x1)

so

y-7 = (-8-7)/(7 +3) * (x+3)

simplify. Thats all

Answer 2

So how basically its a fraction type sort? correct?

Answer 3

If so, how exactly can I do the top? I can do the bottom no problem but idk about the y-7 part

Answer 4

so,
y-7 = (-15/10) * (x+3)

10 (y-7) = -15(x-3)
10y - 70 = -15x + 45

Therefore,

10y + 15x - 115 =0
Now divide by 5 throughout

2y + 3x - 23 = o

Answer 5

Wowww that makes a lot more sense... I feel dumb haha. Thank you soooo much
