Writing Linear Functions 1.9 - Solution

arrow_back Return to Writing Linear Functions

To write the equation in slope-intercept form, we should find the slope and the -intercept first. The -intercept is the point at which the line intercepts the -axis. We can identify it from the graph!

We can tell that the -intercept is Now to find the slope, let's identify one more point on the line and use the slope formula.

As we can see the line passes through the points and Let's substitute them in the slope formula and simplify!
Now that we found the slope and the -intercept, we can write the equation of this line in the slope-intercept form
