Answer:


  • \boxed{\sf{y=-5x+8}}

Explanation:

You can solve this problem using the slope formula and slope-intercept formula.

Slope formula:


\Longrightarrow: \sf{m=(y_2-y_1)/(x_2-x_1)=(rise)/(run) }

Slope-intercept formula:


\Longrightarrow: \sf{y=mx+b}

  • M: represents the slope.
  • B: represents the y-intercept.

(1,3) and (2,-2)

y2=(-2)

y1=3

x2=2

x1=1

Rewrite the problem.


\sf{(-2-3)/(2-1)=(-5)/(1)=-5 }

  • The slope is -5.

  • y-intercept is 8.

Rewrite the problem.

y=-5x+8

  • Therefore, the correct answer is y=-5x+8.

I hope this helps you! Let me know if my answer is wrong or not.
