Question

Write the equation of the line with a slope of -1 through the point (-2,5)

Answer 1

Answer: I believe its x + y = 3.

Explanation:

Answer 2

y = -x + 3

Explanation:

In order to write the line's equation, we are going to use the point-slope formula.

`\sf{y-y_1=m(x-x_1)}`

Put in the values :

• 
  `\sf{y-5=-1(x-(-2)}`
• 
  `\sf{y-5=-1(x+2)}`
• 
  `\sf{y-5=-(x+2)}`
• 
  `\sf{y-5=-x-2}`
• 
  `\sf{y=-x-2+5}`
• 
  `\boxed{\sf{y=-x+3}}`
