I need help solving this
Kruka [31]

Answer: y = -x + 5

Step-by-step explanation:

      A slope-intercept equation is in the form y = <em>m</em>x + <em>b</em> where <em>m</em> is the slope and <em>b</em> is the <em>y</em>-intercept. Since we are given the slope, we will plug it in with the point they gave us, and solve for <em>b</em>.

y = <em>m</em>x + <em>b</em>

(1) = (-1)(4) + <em>b</em>

1 = -4 + b

5 = b

      Lastly, we will write our equation by substituting <em>m</em> with -1 and <em>b</em> with 5.

y = <em>m</em>x + <em>b</em>

y = -1x + 5 or y = -x + 5
