Need help finishing this table for the equation y= 4x - 1
The value of x is -2, -1, 0, 1, 2, 3 so below each of those values what is
The value of y
I think I got it. THANKS
When you sub in the value of -2 into your equation you obtain
y = 4x - 1
y = (4) times (-2) - 1
y = -8 - 1
y = -9
follow this similar procedure to figure out the values that go with each x value that you sub into the equation.
To complete the table for the given equation y = 4x - 1, we can substitute each given value of x into the equation and calculate the corresponding value of y.
Let's find the value of y for each given value of x:
When x = -2:
y = 4(-2) - 1
= -8 - 1
= -9
When x = -1:
y = 4(-1) - 1
= -4 - 1
= -5
When x = 0:
y = 4(0) - 1
= 0 - 1
= -1
When x = 1:
y = 4(1) - 1
= 4 - 1
= 3
When x = 2:
y = 4(2) - 1
= 8 - 1
= 7
When x = 3:
y = 4(3) - 1
= 12 - 1
= 11
Now you can complete the table as follows:
x | y
--------------
-2 | -9
-1 | -5
0 | -1
1 | 3
2 | 7
3 | 11
To find the value of y for each given value of x, you can substitute the given values of x into the equation y = 4x - 1 and calculate the corresponding values of y. Here's how you can do that:
1. For x = -2:
Substituting this value into the equation, we have:
y = 4(-2) - 1
y = -8 - 1
y = -9
2. For x = -1:
Substituting this value into the equation, we have:
y = 4(-1) - 1
y = -4 - 1
y = -5
3. For x = 0:
Substituting this value into the equation, we have:
y = 4(0) - 1
y = 0 - 1
y = -1
4. For x = 1:
Substituting this value into the equation, we have:
y = 4(1) - 1
y = 4 - 1
y = 3
5. For x = 2:
Substituting this value into the equation, we have:
y = 4(2) - 1
y = 8 - 1
y = 7
6. For x = 3:
Substituting this value into the equation, we have:
y = 4(3) - 1
y = 12 - 1
y = 11
So, completing the table, the values of y corresponding to each given value of x are as follows:
x | y
--------------
-2 | -9
-1 | -5
0 | -1
1 | 3
2 | 7
3 | 11
