Question

How do you write the standard form of the equation given (3,-1) and slope -1?

Answer 1

Standard form: `y=mx+b`, where `m` is the slope and `b` is the y-intercept.
`y=-1` and `x=3` and `m = -1`
In order to find `b`, plug in knowns, listed above.
`-1 = -3 + b`
To solve for `b`, move `-3` to the other side of the equation.
`-1+3=b`
`b=2`
Standard form equation: `y=-x+2`
