Question

Q3. A certain line has a slope of 3 and contains the point (-5,0). Which of the following points are on the same line? Select all that apply.

A. (-9, -12)
B. (-6, -3)
C. (-3, 6)
D. (0, -15)

Answer 1

Answer:

A and B and C are correct

Step-by-step explanation:

y = mx + b

m = 3

b = y - 3x =0 - 3 x (-5) = 15

y = 3x + 15

for (-9, -12) : y = - 12   y = 3 x (-9) + 15 = -12     ... correct

for (-6, -3) : y = -3     y = 3 x (-6) + 15 = - 3  ..... correct

for (-3, 6): y = 6      y = 3 x (-3) + 15 = 6   ......Corect

for (0, -15): y = - 15    y = (3 x 0)  + 15 = 15  .... Wrong
