Write the equation of the line that is parallel to the line y = -3x + 12 and passes through the point (-1, 6).

Question

 i need help please in algebra 1. please and thank you.

Answer 1

Two lines are parallel if the slopes of each are equal.

 

y = -3x + 12, the slope is -3

)

Use the point-slope form      m(x - x₁) = (y - y₁)

 

-3(x - (-1)) = (y - 6)

-3(x + 1) =  y - 6       

-3x - 3 = y - 6

-3x + 3 = y
