Answer:
f(x) = x
Step-by-step explanation:
The first thing we need to find is the slope of the line able to pass through the given two points. Right now we have <em>y = mx + b</em> (linear function equation) and we need to find <em>m</em>.
- Using the slope formula or
and plugging in the given points' x and y values:
=
=
- The slope of the line is that for every 5 units the line goes upwards, it goes 2 units to the right.
Our equation is now <em>y = x + b</em>. If you were in need of it, <em>b </em>gives the line's y-intercept, the place where it hits the y-axis. In this case you do not need <em>b</em> because the only specified conditions in the problem are the units the line hits.
Our final equation is:
f(x) = x
