Question

The graph of which function(s) will contain the point (2, 10)?

y = 5 x
y = 8 x
y = 10 - x
y = x + 8

Answer 1

(a), (d)

Explanation:

Use x=2 and evaluate:

(a) y = 5(2) = 10 . . . . (2, 10) is on the graph

(b) y = 8(2) = 16

(c) y = 10 -2 = 8

(d) y = 2 +8 = 10 . . . . (2, 10) is on the graph
