Question

State the equation, in slope-intercept form, of each of the following graphs of linear relations. Explain how the equation was determined.

Answer 1

Answer: y=-3x or y=-3x+0

Step-by-step explanation:

First of all, we can tell that our y-intercept is zero and we don't have to add that to our finished equation. Next, we can can perform a rise rise over run to find the slope (-3x).

I chose the points (-3, 9) and (-2, 6).

If you like the method y2-y1/x2-x1 you could use the second y value, subtract it by the first and do the same with the x.

Hope this helps!!
