Which equation of a line has a slope of -3 and passes through point (2, 4)?

y = 3x + 10

y = -3x + 10

y = 3x – 10

y = -3x – 10

Respuesta :

Answer:

B

Step-by-step explanation:

y-4 = -3(x-2)

y - 4 = -3x + 6

y = -3x + 6 + 4

y = -3x + 10

Answer:

y = -3x+10

Step-by-step explanation:

Using the slope-intercept equation of a line

y = mx+b  where m is the slope and b is the y intercept

y = -3x+b

Substitute the point into the equation

4 = -3(2) +b

4 = -6+b

10 =b

y = -3x+10
