Question

Make this graph into y=mx+b form​

Answer 1

Answer: y=-3x-5

Explanation:

(0,-5) (-1,-2)

`\displaystyle\\(x-x_1)/(x_2-x_1) =(y-y_1)/(y_2-y_1)`

x₁=0 x₂=-1 y₁=-5 y₂=-2

`\displaystyle\\(x-0)/(-1-0)=(y-(-5))/(-2-(-5)) \\\\(x)/(-1) =(y+5)/(-2+5) \\\\-x=(y+5)/(3)`

Multiply both parts of the equation by 3:

`-3x=y+5\\\\-3x-5=y+5-5\\\\-3x-5=y`

`Thus,\ y=-3x-5`
