Question

30. Write an equation in point-slope form for the line through the given point with the given slope. (-7,9); m=4/5

A. y+7= 4/5(x-9)
B. y-7=4/5(x+9)
C. y-9=4/5(x+7
D. y+9=4/5(x-7)

Answer 1

Please I need help. Dx

Answer 2

What's the problem here?

Equation of straight line in the point-slope form:

y − y1= m ( x − x1 )

In this case:

m = 4 / 5 , x1 = - 7 , y1 = 9

y − 9 = ( 4 / 5 ) [ x − ( - 7 ) ]

y − 9 = ( 4 / 5 ) ( x + 7 )
