Question

Write the equation of the line that passes through (–1, 5) with a slope of 2 in standard form.

Answer 1

y=mx+c
5=2(-1) +c
c= 7
therefore
y=2x+7

Answer 2

use y-y1 = m(x-x1)
m=2 and x1,y1 = -1,5
so
y-5 = 2(x-(-1))
y = 2x + 2 +5
2x - y = -7

Answer 3

i'm from uk so i'm not sure what standsad form is in us
ik uk its ax + by = c

Answer 4

y = mx + b is also a "standard form", confusing I think..
