Question

What is the equation of the line that has a slope of -1 and goes through point (0, 5)?
Answer

y = -x + 5

y = -2x + 5

y = -x

y = 2x + 5

Answer 2

i would use pint slope form
Y - 5 = -(x)
Y = -x+5

Answer 3

Hey, Mr. Kool.
I love multiple choice questions because you can do process of elimination.
We know the equation needs a slope of -1.
So only the first and third choice qualify.
Then, just mentally substitute (0,5) in the second and fourth choice to see which ends up giving a true statement.
Yup, it's the first of the four choices!

Done!

Hope that helped.

Answer 4

point-slope form (use when given a point and a slope)
\[(Y-Y _{1}) = m(X-X _{1})\]
slope intercept form
y = mx+b
