6. Which equation represents the equation that passes through the given points:
(1,5) & (3,-3)
A. y = 2x + 3
B. y = -4x +9
C. y = 2x – 9
D.y = - 4x +3

Respuesta :

The answer is B

Find slope

                       y2 - y1

Formula:         x2 - x1

Just plug in values

Slope will be -4

Take equation and plug in a point

Equation:  y = mx + b

Plug in    5 = -4(1) + b

                5 = -4 + b

              +4   +4            

               9 = b

         

                 y = -4x + 9
