Write an equation that is parallel to y=-4x+5 and passes through the point (-2,-1)

Answer 1

any parallel line has the same slope, so any parallel line will have the form

y=-4x + b, where b = the y intercept = any number other than 5. to calculate b plug in the point

-1 = -4(-2) + b

b = -1 -8 = - 9

y= -4x - 9 is the equation parallel through the given point
