Question

Write the equation of the line that passes through (–1, 4) with a slope of –1 in standard form

Answer 1

y = mx+b

y = -1x+ b ... plug in m = -1

y = -x + b

4 = -1*(-1)+b ... plug in x = -1 and y = 4

Now solve for b

Answer 2

Remember to convert to standard form

Answer 3

x+y=3.. wait that isn't standard form

Answer 4

?

Answer 5

that's standard form and it's 100% correct, nice work
