A data table shows that as the input (x) increases by 1, the output (y) decreases by 7. When x is 0, y is –2. What is the equation for this function? A. y = 7x – 2 B. y = 7x C. y = –7x – 2 D. y = –7x + 2

Respuesta :

x   0   1    2    ...
y  -2  -9 -16...
(y) decreases by 7/ (x) increases by 1, so slope =-7,
y- int=-2
this is equation c) y=-7x-2
