Answer: y = 2x + 8
Step-by-step explanation:
The first thing we must do to find the equation of the linear function in y intercept form is to calculate the slope. Recall that the slope is rise over run, or the y displacement divided by the x displacement. On this graph, we can tell that for each time the line moves horizontally, it moves twice the distance upwards, which means that the slope m is equal to 2/1, or 2.
Second and last,we need to also find b, the y intercept. This particularly easy because is just where it crosses the y axis. If you look, can tell that it crosses at y=8, so b is 8.
Now, all we have to do is plug in our values to get the final answer of y = 2x
+8
