Answer:
x--------------y
4--------------2
8--------------3
12-------------4
Step-by-step explanation:
y = 1/4x + 1
We substitute the values under x into the equation
Equation 1: y = 1/4(4) + 1
Equation 2: y = 1/4(8) + 1
Equation 3: y = 1/4 (12) + 1
Let's solve for equation 1:
Equation 1: y = 1/4(4) + 1
y = 1/4(4) + 1
Multiply number in parenthesis
y = 1/4 * 4/1 + 1
1/4 and 4/1 turn into 1
y = 1 + 1
Add 1 to 1
y = 2
Let's solve for equation 2:
y = 1/4(8) + 1
Multiply number in parenthesis
y = 1/4 * 8/1 + 1
1/4 and 8/1 turn into 2
y = 2 + 1
Add 2 to 1
y = 3
Let's solve for equation 3:
y = 1/4 (12) + 1
Multiply number in parenthesis
y = 1/4 * 12/1 + 1
1/4 and 12/1 turn into 3
y = 3 + 1
Add 3 to 1
y = 4
So the table of values would be:
x--------------y
4--------------2
8--------------3
12-------------4
