Question

If y = 2x - 1 and (3,5) and (4,7) are part of the pattern then what is the y coordinate of (5._)?

A 8
B 9
C 10
D 11​

Answer 1

Explanation:

y = 2x - 1

(5,?).....so we know that x = 5....so sub in 5 for x in ur original equation and find y

y = 2x - 1

y = 2(5) - 1

y = 10 - 1

y = 9.....so ur point is (5,9).....with y being 9
