Question

How do you write an equation of the line that passer through points (0, 7) and (1, 10)?

Answer 1

Rhis line has equation `y=3x+7`. See explanation.

Explanation:

A general equation of a linear function can be written as `y=ax+b`

Since one of the given points is the function's Y-intercept we can write that `b=7`.

Now we have to ind a value of `a` for which `(1,10)` belongs to the graph. If we substitute the given values we get:

`10=a+7`

`a=3`

So finally the function is `y=3x+7`
