Question

What is the equation of a line, in general form, with a slope of -2 and a y-intercept of 8?

x + 2y - 8 = 0
2x + y - 8 = 0
2x - y + 8 = 0

Answer 1

it is easier to write it first in 'slope intercept' form

y = mx+ b

m is th eslope
b is th eintercept

after you have done that it is straightforward to re-arrange it to standard form....just subtract y from each side of the equation.
