Question

What are the values for y when x is 1, 2, and 3?y = 10x + 9

Answer 1

we have the equation

y=10x+9

Part 1

Find out the value of y when the value of x=1

so

For x=1

substitute the value of x in the given equation

y=10(1)+9

y=10+9

y=19

Part 2

For x=2

substitute the value of x in the given equation

y=10(2)+9

y=20+9

y=29

Part 3

For x=3

y=10(3)+9

y=30+9

y=39
