Question

Write a linear equation to: slope=2 and goes through point (4, 11)

Answer 1

When you have to write a linear equation and you have the slope (m) and a point (4, 11) you:

1. Use the standard form of a linear equation:

`y=mx+b`

You know the value of:

m= 2

y= 11

x= 4

You make a substitution:

`11=(2)(4)+b`

You can find then the value of b:

`11=8+b`
`b=11-8=3`

Then you have now the data to form the final linear equation:

`y=2x+3`
