Answer:
A, C, D, E
Step-by-step explanation:
We can make an equation with the information given using slope-intercept form [ y = mx + b ]. m = slope and b = y-intercept.
y = 4/7x - 9
Let's check to see which points are on the line.
(14, -1)
-1 = 4/7(14) - 9
-1 = 8 - 9
-1 = -1
TRUE
(1, 9)
9 = 4/7(1) - 9
9 = 4/7 - 9
9 = -8 3/7
FALSE
(0, -9)
-9 = 4/7(0) - 9
-9 = -9
TRUE
(21, 3)
3 = 4/7(21) - 9
3 = 12 - 9
3 = 3
TRUE
(7, -5)
-5 = 4/7(7) - 9
-5 = 4 - 9
-5 = -5
TRUE
(4, 7)
7 = 4/7(4) - 9
7 = 16/7 - 9
7 = -47/7
FALSE
Best of Luck!
