Question

which of the following is a point on the line which passes through (-3,-17) and (12,-7)?
A. (75,33)
B. (75,35)
C. (75,37)
D. (75,39)
E. (75,41)

Answer 1

start by finding an equation of the line. slope is (-7+17)/(12+3)=10/15=2/3
using point slope form y+17=(2/3)(x+3)
y=2/3x-15

plug in x=75

y=(2/3)*75-15
y=50-15=35

so (70,35) is on the line
