Question

Which group of points lies on the line y = 4x - 3? (1, 1); (2, –1); (–1, –7) (1, 1); (2, 5); (-1, –1)
(1, 1); (2, 5); (–1, –7) (1, 1); (2, –1); (–1, –1)

Answer 1

y=4x-3
(1,1)
1=4*1-3
1=4-3
1=1
(2,-1)
(-1)=4*2-3
(-1)=9-3
(-1)=6
(-1,-7)
(-7)=4*(-1)-3
(-7)=(-4)-3
(-7)=(-7)
(1,1)
1=4*1-3
1=4-3
1=1
(2,5)
5=4*2-3
5=8-3
5=5
(-1,-1)
(-1)=4*(-1)-3
(-1)=(-4)-3
(-1)=(-7)
