Question

How do you write an equation in standard form for a line which passes through points (1,1) with slope of 1.2?

Answer 1

The answer is : `y = 1.2x -0.2`

Any linear function has the following form : `y = mx + b`, where `m` is the slope.

So if `m = 1.2`, you have :

`y = 1.2x + b`

Since you have the point `(x,y) = (1,1)`, you can find `b` by solving the above equation :

`y = 1.2x + b => 1 = 1.2*1+b => b=-0.2`

Now you have your answer :

`y = 1.2x -0.2`
