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

Solve the inequality for x.
ahrayia [7]

Answer:

B) x < –8

Step-by-step explanation:

–2x – 3 > 13

Add 3 to each side

–2x – 3+3 > 13+3

-2x > 16

Divide each side by -2, remembering to flip the inequality

-2x/-2 < 16/-2

x < -8
