3
?
D
1

Answer 1

If value of x = 3, y = 28

If value of x = 2, y = 18

If value of x = -1, y = -12

If value of x = 1, y = 8

Explanation:

Given expression;

y = 10x - 2

Find:

Value of y,

if x = 3

x = 2

x = -1

x = 1

Computation:

If value of x = 3

y = 10x - 2

y = 10(3) - 2

y = 30 - 2

y = 28

If value of x = 2

y = 10x - 2

y = 10(2) - 2

y = 20 - 2

y = 18

If value of x = -1

y = 10x - 2

y = 10(-1) - 2

y = -10 - 2

y = -12

If value of x = 1

y = 10x - 2

y = 10(1) - 2

y = 10 - 2

y = 8
