Which of the points below are on the line that passes through (-2, 10) and (1, 4)?

Question

the options is

A. ( 2,0 )

B. ( 2,2 )

C, ( 2,4 )

D. ( 2,-2 )

Answer 1

(-2,10) and (1,4) have a line through them with slope = (10-4)/(-2-1) = -6/3 = -2

the equation is

y = -2x +b. solve for b by plugging in either point, such as x=1,y=4

4 = -2 +b

b =6

y= --2x +6 is the line's equation

B) (2,2) is on the line

2=-2(2)+6 = -4+6 = 2

points in A, C and D aren't
