We need to express y – 2 = 4(x – 3) in the form of:
y = mx + c
y – 2 = 4(x – 3)
Expand the bracket
y - 2 = 4x - 12
Add 2 to both sides
y = 4x - 10
∴ the linear function is:
y = 4x - 10
y = mx + c
y – 2 = 4(x – 3)
Expand the bracket
y - 2 = 4x - 12
Add 2 to both sides
y = 4x - 10
∴ the linear function is:
y = 4x - 10
