Answer:
Step-by-step explanation:
Use the slope-intercept form:
m is the slope and b is the y-intercept. The y-intercept is the place where x is equal to 0, and the slope is the change in the y-axis over the change in the x-axis, otherwise known as rise over run ( ).
If you study the graph, you can see that the line crosses the y-axis at (0,3), so 3 is the y-intercept. Insert into the formula:
Now find the slope. Use the slope formula:
You need two points first. You can use the y-intercept (0,3) and another even point, like (1,6). Insert the values:
The slope is 3. Insert this value:
