Write an equation in slope-intercept form for the line that has a slope of -4 and passes through (1, 2).

A. y = -2x + 4
B. y = -4x + 2
C. y = -4x + 6
D. y = -4x + 9

Respuesta :

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

y-2 = -4(x-1) ... plug in the given info; solve for y

y-2 = -4x+4

y = -4x+4+2

y = -4x+6

Answer is choice C

Answer:

C.   y = -4x + 6

Step-by-step explanation:

First write it in point-slope form ( because that is what you are given):-

y - y1 = m(x - x1):-

y - 2 = -4(x - 1)

y - 2 = -4x + 4

y = -4x + 6 (answer)
